Well. Typically I review the code and say “what kind of twisted sadistic prick wrote this” and then realize that it was me 5 months ago. It’s amazing the level a detail a person can drill into when it’s the locus of focus, and amazing how quickly context is forgotten. Stream of consciousness audio notes would arguably be more useful in such settings than code completion, as the muscle memory is still there, it’s merely the “why” that disappears
