Thanks! I should have mentioned that I had read that post and the very interesting Pure Perl tail call optimization in my RTFM search prior to my post. I wasn't able to find an answer to my question, which is simply whether if I write a recursive procedure like factorial_iterative, which looks like it ought to generate an iterative process, does it in fact execute in a constant memory space like it looks like it should, or does it's memory usage grow linearly the way factorial_recursive looks like it should.

Perhaps my question is foolish and someone wiser than I could show me the error of my ways.
