This list catalogs class builders for classes that use array (instead of the
popular hash) as their backend storage.

Hash is the vastly popular backend for object due to its flexibility and
convenient mapping of hash keys to object attributes, but actually Perl objects
can be references to any kind of data (array, scalar, glob). Storing objects as
other kinds of references can be useful in terms of attribute access speed,
memory size, or other aspects. But they are not as versatile and generic as
hash.

This application not only lets you download a CPAN mini mirror (using
<pm:CPAN::Mini> actually) but also index the package list and distribution
metadata into a SQLite database so you can perform various queries, like list of
modules/distributions/scripts of a CPAN author, or related modules using
cross-mention information on modules' PODs, or various rankings.

versions of a distribution as long as the CPAN author does not clean up his
previous releases). This produces a significantly smaller CPAN mirror which you
can use on your PC/laptop for offline development use.

            print "Module $mod is installed";
            last;
        }
    }

Or you can use something like <pm:Module::Path> or <pm:Module::Path::More> which
does similar to the above.

A module can also be loaded from a require hook in ~@INC~ (like in the case of
fatpacked or datapacked script) and the above methods does not handle it.
Instead, you'll need to use <pm:Module::Load::Conditional>'s `check_install` or
<pm:Module::Installed::Tiny>'s `module_installed`:

    use Module::Load::Conditional qw(check_install);
    if (check_install(module => "Foo::Bar")) {
        # Foo::Bar is installed
    }

The above does not guarantee that the module will be loaded successfully. To
check that, there's no other way but to actually try to load it:

=head2 Working with tree data structure in Perl

B<Basics>

Perl classes to represent tree (node) structure: L<Tree::Object> and
L<Tree::ObjectXS> (comes with several varieties). They provide methods like
walking a tree, checking whether a node is the first child, getting sibling
nodes, and so on.

Perl modules to manipulate tree: L<Data::Tree>, L<Tree::Simple>.
