Unless you're me. Or Damian. Or a fair number of other programmers who like to dive into the Perl Dark Side on a regular basis. > -- requiring it to be explicit seems reasonable. It seems so. Knowing Larry, I'm sure this is an ungrounded fear, but I definitely want to be able to declare in a module "I'm going to be screwing with stuff; keep out of my way," so that I don't impose any awkward declarations on my module users. If that request can be made more explicit in the cases where that's possible, great, but the general declaration should be available. Luke > > >I'm probably spouting nonsense.
