        A couple of comments: <br><br>* Some functions like min(), max(),
        etc need not be reinvented because they are already in core module
        List::Util. But I guess the author wants to be able to say
        min([1,2,3]) in addition to min(1,2,3). <br><br>* round() uses
        Number::Format, note that rounding number using this module is
        hundreds of times slower than using sprintf(). <br><br>

    Submodules
        Author: ZARABOZO <https://metacpan.org/author/ZARABOZO>

        A couple of prior arts: <br><br>* all, <a
        href="https://metacpan.org/pod/all"
        rel="nofollow">metacpan.org/pod/all</a> (since 2003), nicer
        interface and offers &quot;use&quot;/compile-time interface, so it's
        more equivalent to the statements it wants to replace. The
        Submodules equivalent would be: BEGIN { for my $i
        (Submodules-&gt;find(&quot;Blah&quot;)) { $i-&gt;require } }.
        <br><br>* Module::Require, <a
        href="https://metacpan.org/pod/Module::Require"
        rel="nofollow">metacpan.org/pod/Module::Require</a> (since 2001),
        also nicer interface, more flexible, and more lightweight
        implementation. <br><br>I don't like Submodules' interface, it's too
        verbose and clunky. IMO, the interface should be a one-liner and
        without manual looping.

    Regexp::Assemble
        Author: RSAVAGE <https://metacpan.org/author/RSAVAGE>

        I guess it depends on your data, but for random shortish strings
        (hundreds to thousands of them), I find that using raw joining is
        much faster to assemble the regex. And the resulting regex is also
        (much) faster to match. Please see Bencher::Scenario::RegexpAssemble
        if you're interested in the benchmark script.

    Tie::Scalar::Callback
        Author: DFARRELL <https://metacpan.org/author/DFARRELL>

        There is a prior art Tie::Simple (created in 2004) which works for
        scalar as well as the other types of ties that perl supports (array,
        hash, handle). <br>

    JSON::Create
        Author: BKB <https://metacpan.org/author/BKB>

        Review for 0.02: Performance-wise, still has some catching up to do
        against JSON::XS &amp; Cpanel::JSON::XS with regards to encoding
        arrays &amp; hashes. <br><br>UPDATE review for 0.19: Giving it 4
        stars now. Speed has been improving and on-par/slightly better than
        the other JSON XS modules in some areas, while a bit worse in some
        other areas. Faster modules are always welcome.

    Set::Scalar
        Author: DAVIDO <https://metacpan.org/author/DAVIDO>

        Confirming previous reviewer, the module is a lot slower (~ 20-40x)
        than other alternatives like Array::Utils or List::MoreUtils when
        you want to perform basic set operations like
        union/intersect/diff/symmetric diff.

    Exporter::Easy
        Author: NEILB <https://metacpan.org/author/NEILB>

        I can see the value of Exporter::Easy (although these days the
        saving in typing is not as big, with plain Exporter one can just
        say: use Exporter 'import'; our @EXPORT = qw(a b c)).
        <br><br>However I fail to see the value of Exporter::Easiest. I'd
        rather use plain Perl than some DDL which cannot be checked
        statically or cannot be syntax-highlighted, just to save some []'s
        and ()'s (which I can get my editor to help me type them).
        <br><br>In short, I'd rather use plain Exporter than save a few
        keystrokes but add a non-core dependency.

    App::cpm
        Author: SKAJI <https://metacpan.org/author/SKAJI>

        Due to parallel processes and defaulting on no_test, can be several
        times faster than cpanminus (tried installing a module on a vanilla
        perlbrew instance with local CPAN mirror, which pulled +- 200
        distributions, &quot;cpanm -n&quot; took 2m9s, while cpm took 38s.)
        I hope this gets developed further. Great job. <br>

    Zodiac::Chinese
        Author: CAVAC <https://metacpan.org/author/CAVAC>

        From the doc: &quot;This module generates one's Chinese zodiac.
        However, for those born in late January to early February, it may be
        wrong.&quot; Well, a module that might return wrong results is not
        very useful. <br>

    JSON::MultiValueOrdered
        Author: TOBYINK <https://metacpan.org/author/TOBYINK>

        I guess if you want to switch JSON implementation more easily with
        JSON, JSON::PP, and JSON::XS, it's better to use
        JSON::Tiny::Subclassable instead of JSON::Tiny, because the
        interface is more similar to JSON{::XS,::PP}, although it's not
        exactly the same. JT:Subclassable also supports pretty() which is
        often used when debugging. In short, I found
        JSON::Tiny::Subclassable is a better &quot;Tiny JSON&quot; module
        than JSON::Tiny.

    JSON::Tiny
        Author: DAVIDO <https://metacpan.org/author/DAVIDO>

        Ah, the many JSON implementation modules out there... <br><br>I
        guess if you want to switch JSON implementation more easily with
        JSON, JSON::PP, and JSON::XS, it's better to use
        JSON::Tiny::Subclassable instead of JSON::Tiny, because the
        interface is more similar to JSON{::XS,::PP}, although it's not
        exactly the same. <br><br>

    Devel::Confess
        Author: HAARG <https://metacpan.org/author/HAARG>

README  view on Meta::CPAN

        print/return the ref/object and thus no stack trace information is
        produced. <br><br>See also Devel::Confess, which can handle
        ref/object. <br><br>References: <br> <a

    experimental
        Author: LEONT <https://metacpan.org/author/LEONT>

        Our prayer has been answered. experimental was added to perl core in
        5.19.11

    Exporter::Lite
        Author: NEILB <https://metacpan.org/author/NEILB>

        Mostly unnecessary. The main premise of this module is that you
        don't need to inherit to use it. But you also can use Exporter (a
        core module, BTW) without inherinting it: <br><br>use Exporter
        qw(import); <br>

    Date::Holidays
        Author: JONASBN <https://metacpan.org/author/JONASBN>

        The idea is good, but a couple of things prevents me from using this
        interface. <br><br>First, the use of TryCatch (which brings the
        Moose ecosystem) makes the startup overhead too high for my taste
        (about 0.5s on my PC). Which is rather unfortunate because
        Date::Holidays itself does not use Moose. <br><br>Second, the
        interface assumes that a country has a single set of holidays, which
        is too restrictive in some cases. A more flexible/general interface
        would allow adding more calendars based not only on country but also
        religion, special community, organization, etc. And allow adding
        custom calendars. <br>

    Furl
        Author: SYOHEX <https://metacpan.org/author/SYOHEX>

        @Kira S (I wish cpanratings adds a feature to comment on a review):
        <br><br>Comparing WWW::Mechanize with Furl is not really
        apples-to-apples, since Furl does not support parsing/following
        links or form processing. As the Furl POD itself suggests, Furl is
        positioned as a faster alternative to LWP, not WWW::Mechanize.

    Lingua::EN::Inflect
        Author: DCONWAY <https://metacpan.org/author/DCONWAY>

        Just add this review to link to Ben Bullock's
        Lingua::EN::PluralToSingular if you need to go the other way
        (converting English noun from plural to singular). <br><br>BTW, I
        don't like the interface either, and wonder why the Env module needs
        to be involved. <br>

    Lingua::EN::PluralToSingular
        Author: BKB <https://metacpan.org/author/BKB>

        Not perfect or exhaustive, but good enough and lightweight. With a
        dead-simple interface. Just the sort of libraries that are reusable
        almost everywhere. Thanks for this. <br><br>Also, this might not be
        immediately obvious since there's no mention on the See Also
        section: to go the other way (converting English noun from singular
        to plural) you can use Lingua::EN::Inflect.

    Log::Declare
        Author: CHGOVUK <https://metacpan.org/author/CHGOVUK>

        I haven't used or evaluated this module in detail, but if there is
        one advantage to using procedural/command syntax: <br><br>info blah;
        <br><br>as opposed to object syntax: <br><br>$log-&gt;info(blah);
        <br><br>then this module clearly demonstrates it. Using
        Devel::Declare (or the Perl 5.14+ keyword API), the former can be
        easily rewritten as something like: <br><br>info &amp;&amp; blah;
        <br><br>or: <br><br>if (CONST_LOG_INFO) { info blah } <br><br>and
        during compilation, Perl can optimize the line away and we get zero
        run-time penalty when logging (level) is disabled.
        <br><br>(Actually, it's also possible for the object syntax to get
        rewritten, e.g. using source filter, but it's more cumbersome).

    Benchmark::Timer
        Author: DCOPPIT <https://metacpan.org/author/DCOPPIT>

        Nice alternative module for benchmarking with a different interface
        than Benchmark (marking portion of code to be benchmarked with start
        and stop). <br><br>For most Perl programmers familiar to the core
        module Benchmark, I recommend looking at Benchmark::Dumb first
        though. It has an interface like Benchmark (cmpthese() et all) but
        with some statistical confidence.

    Getargs::Long
        Author: DCOPPIT <https://metacpan.org/author/DCOPPIT>

        Nice idea, but some performance concerns. If you want to use
        cgetargs (the compiled, faster version), you are restricted to the
        getargs() interface, which only features checking for required
        arguments and supplying default value. In which case you might as
        well use Params::Validate directly as it's several times (e.g. 3-4x)
        faster. <br><br>If you want to use the more featured xgetargs, there
        is currently no compiled version. <br><br>All in all, I think users
        should take a look at Params::Validate first.

    Debug::Easy
        Author: RKELSCH <https://metacpan.org/author/RKELSCH>

        Not as easy as the name might claim. First of all, why do users need
        to pass LINE explicitly for every call??? Other logging modules will
        get this information automatically via caller(). <br><br>Levels are
        a bit confusing: why is debug split to 2 (or 3)? <br><br>Not as
        flexible as it should be because the design conflates some things
        together. For example, most levels output to STDERR but some level
        (VERBOSE) outputs to STDOUT instead. The output concern and levels
        should've been separated. Another example would be the DEBUGWAIT
        level, where level is DEBUG *and* execution is halted (wait on a
        keypress) on log. What if users want a lower level setting *but*
        want execution to be halted on log? The halt/keypress setting
        should've been separated from the level.
