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