Interesting. There a bunch of modules that I routinely use that produce warnings under -w. In fact I spent a day trying to figure out what I was doing wrong, only to realize that my colleague had slipped a -w into the script and that nothing was wrong. (Win32::Eventlog is the latter mentioned module)

Personally I think that the late introduction the warnings modules and its consequent slow takeup and usage was one of the few serious language errors that was made in the earlier versions of perl. (Strong words I know, but im entitled to an opinion :-)

I suspect that perl6 will have a quite powerful warning and strictures structure from the get-go as a lesson learned from this.
