No. 5 looks like a pretty cool solution to the problem. There's one thing with this code though that I can't figure out. It looks to me that you're using a closure, but it doesn't work. When I try to run this code Perl complains: Global symbol "$warn" requires explicit package name

I could only make this work by removing the outer { }. Does anyone know why this closure doesn't work?
