=head1 NAME

=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.

=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.
