=head1 NAME
Test2::Tools::Ref - Tools for validating references.
=head1 DESCRIPTION
This module contains tools that allow you to verify that something is a ref. It
also has tools to check if two refs are the same exact ref, or different. None of
the functions in this module do deep comparisons.
=head1 SYNOPSIS
use Test2::Tools::Ref;
# Ensure something is a ref.
ref_ok($ref);
# Check that $ref is a HASH reference
ref_ok($ref, 'HASH', 'Must be a hash')
ref_is($refa, $refb, "Same exact reference");
ref_is_not($refa, $refb, "Not the same exact reference");
=head1 EXPORTS
All subs are exported by default.

=item ref_ok($thing)
=item ref_ok($thing, $type)
=item ref_ok($thing, $type, $name)
This checks that C<$thing> is a reference. If C<$type> is specified then it
will check that C<$thing> is that type of reference.
=item ref_is($ref1, $ref2, $name)
Verify that two references are the exact same reference.
=item ref_is_not($ref1, $ref2, $name)
Verify that two references are not the exact same reference.
