       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.

       All subs are exported by default.

       ref_ok($thing)
       ref_ok($thing, $type)
       ref_ok($thing, $type, $name)
           This  checks that $thing is a reference. If $type is specified then it will check that $thing is that
           type of reference.

       ref_is($ref1, $ref2, $name)
           Verify that two references are the exact same reference.

       ref_is_not($ref1, $ref2, $name)
           Verify that two references are not the exact same reference.

           # 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");
