One recurring complaint is that nobody talks about code on /prog/. So everyone write go and write some code, any code, that does something, anything, and post it. A small explanation wouldn't go amiss either.
>>193 iota isn't in CL, although defining it would be as trivial as something along these lines: (defun iota (count &optional (start 0) (step 1))
(loop repeat count for i from start by step collect i))
I just use LOOP, it works everywhere and has a lot of flexibility. At times I choose to use iter.
