But then, why stop at testing $^W? How about $*? $"? @ARGV?, %SIG? $package::var?

I think you meant this in jest, but this would be a very valuable resource if it could be automated; kind of like the sort of utility that tests for memory leaks in C.

Just being able to know that a given module has tampered with your { global variables/function definitions/namespaces/whatever} is very, very handy.

Perl gives you a lot of rope to hang yourself (and others!) with; having tools to keep it coiled neatly would really be nice sometimes. :-)

    That's a great idea! I think you could add a Policy to Perl::Critic that warns you if a global or package variable was modified without being localized first.
