Re^4: sub calls and memory use

You pass arguments in @_, as always.

So I was just using the wrong global variable! I can see now that pushing my arg into @_ before the &sub call prevents memory growth. Thank you Corion.

In Perl you are generally better off translating tail calls to loops. They are way faster and easier to understand. You never explained your use case, but your example is easily translated with `redo` Concerning your memory growth, we'd need to know how you declared the "global var".

In Perl you are generally better off translating tail calls to loops. I replaced that recursive sub with a while loop and yeah, makes more sense, less code, and no memory bomb.
