There's also perlboot, perlobj and perlbot. perlboot is like perltoot, and
perlbot is the bag of tricks - it's got lots to do with Perl's object
system specifically. perlobj is a sort of reference to Perl's object system.

It also smells to me like a 'has-a' or 'uses' relationship, depending
on how you call those. I don't know - the docs are very vague.

Nothing stops you from writing that in Perl, aside from the fact that
it isn't builtin... =)
Some insightful projects:
and my own project Object::Meta::Plugin implement object systems,
whose objects can interact with perl's builtin object system, but
which work differently.
It's actually much easier than it sounds =)
Someday, when I'll finally learn Ruby like I promised myself, I will
probably enjoy it.
