... BEGIN ... perlobj ... parent ... perspective ..

By the time you load Data::Dumper or whatever, resolution method could have happened

But yeah, I did say I vaguely recall, esp because I didn't feel like digging up history or pinning down the details :)

As for parent... perspective is exactly the point. If you're bothering to write a module to share, you might as well do it right, which is not dickering around with other peoples class data :) delegate (AUTOLOAD or ...)

At least if you monkey patch, warnings will issue "Subroutine %s redefined"

With Moose it happens at run-time, and this doesn't seem to cause any problems.

Sure it does :) Moose Cookbook - Meta Recipe 5 Won't Run
