     assert(...) if DEBUG;

    where "DEBUG" is a constant subroutine, declared using:

     use constant DEBUG => 0;

    or:

     sub DEBUG() { 0 }

    The perl compiler will optimize away and remove the code entirely when
    "DEBUG" is false. But having to add "if DEBUG" to each assertion is
    annoying and error-prone.

    Nowadays, you have several alternatives to have a true, C-like
    assertions. One technique is using Devel::Declare (e.g. PerlX::Assert).
    Another technique is using B::CallChecker (e.g. Assert::Conditional).

FAQ
  What is an Acme::CPANModules::* module?
    An Acme::CPANModules::* module, like this module, contains just a list
    of module names that share a common characteristics. It is a way to
    categorize modules and document CPAN. See Acme::CPANModules for more
    details.

  What are ways to use this Acme::CPANModules module?
    Aside from reading this Acme::CPANModules module's POD documentation,
    you can install all the listed modules (entries) using cpanm-cpanmodules
    script (from App::cpanm::cpanmodules distribution):

     % cpanm-cpanmodules -n Assert

    Alternatively you can use the cpanmodules CLI (from App::cpanmodules
    distribution):

        % cpanmodules ls-entries Assert | cpanm -n

    or Acme::CM::Get:

        % perl -MAcme::CM::Get=Assert -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

    or directly:

        % perl -MAcme::CPANModules::Assert -E'say $_->{module} for @{ $Acme::CPANModules::Assert::LIST->{entries} }' | cpanm -n

    This Acme::CPANModules module also helps lcpan produce a more meaningful
    result for "lcpan related-mods" command when it comes to finding related
    modules for the modules listed in this Acme::CPANModules module. See
    App::lcpan::Cmd::related_mods for more details on how "related modules"
    are found.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional
    steps required beyond that are considered a bug and can be reported to
    me.
