I have a perl module that extensively uses a variable named "$main", which

There is no variable named $main unless you create it. You may be
mistaking the main package in variables like $main::foo.
Or variables like $main'foo.
I don't think I've ever seen this outside Obfu(scation) or golf.
It's good to know something like that is possible, but please don't
use that. Unless of course you do want to confuse someone ;-)
So I take it that you have never used Per4? :-)
