Re: 1) Would it be fair to say that $depth has its ref count increased when the ++$depth is compiled As opposed to when the sub recurse is actually invoked?

And does this mean that the symbol table entry for $depth will persist for the life of the program (allbeit inaccessible), and never be garbage collected, even if the sub recurse is never invoked?

Re: 2) It was reading and trying to digest perlsub that raised the question in my mind. I scanned perlcall - its interesting. Hopefully a few more reads and a few more weeks of immersion in Perl, and it will make more sense. I had looked in perlguts, just long enough to know that I am not ready for that yet.

Thanks.
