=head1 NAME

SortKey::Num::length - String length as sort key

=head1 VERSION

This document describes version 0.002 of SortKey::Num::length (from Perl distribution SortKey-Num-length), released on 2024-01-23.

=head1 SYNOPSIS

 use Sort::Key qw(nkeysort);
 use SortKey::Num::length;

 my $by_length = SortKey::Num::length::gen_keygen;
 my @sorted = &nkeysort($by_length, "food", "foolish", "foo");

=head1 DESCRIPTION

This is just a demonstration module for L<SortKey>. You might just as well use
Perl's builtin C<length()> directly:

 nkeysort { length shift } ...

=for Pod::Coverage ^(meta|gen_keygen)$

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.

Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=SortKey-Num-length>

When submitting a bug or request, please include a test-file or a
