=head1 NAME

Test2::Require::Perl - Skip the test unless the necessary version of Perl is
installed.

=head1 DESCRIPTION

Sometimes you have tests that are nice to run, but depend on a certain version
of Perl. This package lets you run the test conditionally, depending on if the
correct version of Perl is available.

=head1 SYNOPSIS

    # Skip the test unless perl 5.10 or greater is installed.
    use Test2::Require::Perl 'v5.10';

    # Enable 5.10 features.
    use v5.10;
