=head1 NAME
Test2::Compare::Meta - Check library for meta-checks
=head1 DESCRIPTION
Sometimes in a deep comparison you want to run extra checks against an item
down the chain. This library allows you to write a check that verifies several
attributes of an item.
=head1 DEFINED CHECKS
=over 4
=item blessed
Lets you check that an item is blessed, and that it is blessed into the
expected class.
=item reftype
Lets you check the reftype of the item.
=item this
Lets you check the item itself.
=item size
Lets you check the size of the item. For an arrayref this is the number of
elements. For a hashref this is the number of keys. For everything else this is
undef.
