there are no sweeter words than "I told you so". ;-)

Yeah, I'm starting to see that about you :-)

Points well taken about require vs. use, and @ISA. The very first example in the Synopsis has long done what I need it to do. Maybe it's time for a documentation patch to de-emphasize the older calling convention? No reason for it to have top billing if it's not recommended for new code. Anyway, I'll definitely be adopting this advice going forward. Thanks.

OOP modules should not export methods, as others have explained.

Yes, I was the first to explain that, some hours before your reply.
