It is for precisely this reason why I am one of those truly annoying people who actually writes (a lot of) comments. I have come back to code after as few as 6 months & not recognized it whatsoever.

(Dons Flame-retardant suit) This is especially true of perl code, since TIMTOWTDI, I often change my approach based on my latest definition of "elegant"...

Upon reflection it occurs to me that when writing in a language that is new to me I often write pseudo-code skeletons in comments which I then fill in with the proper syntax once I figure out how to make it work. What I find interesting is that it's not a bad approach to take in general, but I seem to lose interest when fluency sets in.
