Thanks for the advice Dan. I took it to heart. Was, most probably, a case of premature optimization. Hoping for "here ya go, use this" or the joy of creating my first iterate generator. I just converted my 20,000 LOC project from loop to iterate and, wow, just give me some more cool-aid, i'm hooked!
