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!

Note that unless these lists are very big, the cost of doing the append isn't that high. If this code isn't executed a whole lot, it might not be worth trying to avoid the append. (Modern GC's are a lot better than old ones.)

Hello all,
Does anyone have a generator that allows for iteration on multiple lists sequentially without creating a single list.
I'm doing this alot:
(iter (for el in (append list1 list2 list3)))
when the APPEND is really not necessary with a sufficiently smart generator like:
(iter (for el in list then list2 then list3)))
?
Thank you, Will
