On further thought, I'll claim that putting the following to overload
stringification for a class:
'""' => sub { shift->tid() }
should affect the behavior of $$ref and not $ref. That is, the thing
being overloaded is the class and not the reference so "$ref" should
continue to do what the "reference" type says that stringification
should do (that is, return the referenced class name plus unique id)
while "$$ref" should use the stringification rule for the class that is
being referenced.
Yeah, that's really going to bring on the 'backwards compatibility
police' as a *big* change in behavior. You can't just make stuff up
like that cause you feel like it. ;-)
I spent close to two years spelunking inside the Perl core and
documenting how overloading functions in XS. Perl objects are the
references to other things, not the other things themselves (i.e.
blessing an anonymous hash makes an object, but the hash is still just a
hash).
