I believe that's a matter of opinion, but point taken.

I'm not quite sure what you mean here. Recursive subs can use global variables the same way as any sub can.

Sure they can use globals, but that's not the recursive part. I agree with the remainder of your response though. You just said it better than I did.

With Perl, this is a pretty big deal.

Agreed, as long as you take into context the power of the machine its running on. That makes both C and Perl speed relative.

Overall, I like you comments. You added a lot of clarity that I didn't express very well.
