#NAME

Test2::Tools::Ref - Tools for validating references.

#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.

#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");

#EXPORTS
