There's currently a thread on p5p where some people argue that the non-aliasing behaviour of given is a bug. I kind of like the idea that since one can use when clauses in a for, given doesn't alias. If you want aliases, write for; otherwise, write given. OTOH, I don't think I've ever written code where I wanted given to alias, nor that I wanted it to not-alias. That is, each time I use given, whether $_ aliases or not, it does not matter.
