[And lots of other warnings]

This is the result of a small philosophical rift between me & Chris. As opposed
to Chris, I don't believe in making modules -w clean at any price (they are
all strict clean, however), and since warnings are currently global, this
interferes with the practice of putting -w on the #! line (which, BTW, is
increasingly considered a bad idea for production code, but a good one in 
development).

Future versions of perl will have a finer grain scoping of -w, so it's possible
to turn warnings on for one's own code while leaving them off for modules.
