=head1 NAME
Test2::Util::Ref - Tools for inspecting or manipulating references.
=head1 DESCRIPTION
These are used by L<Test2::Tools> to inspect, render, or manipulate references.
=head1 EXPORTS
All exports are optional. You must specify subs to import.
=over 4
=item $type = rtype($ref)
A normalization between C<Scalar::Util::reftype()> and C<ref()>.
Always returns a string.
Returns C<'REGEXP'> for regex types
Returns C<''> for non-refs
Otherwise returns what C<Scalar::Util::reftype()> returns.
=item $addr_str = render_ref($ref)
Always returns a string. For unblessed references this returns something like
C<"SCALAR(0x...)">. For blessed references it returns
C<"My::Thing=SCALAR(0x...)">. The only difference between this and C<$add_str =
"$thing"> is that it ignores any overloading to ensure it is always the ref
address.
