This is a trip, seeing code I wrote 25 years ago. It's actually kind of scary how identifiable my style is; in a lot of ways I am still the same coder, although I tend to work at a much higher level of abstraction now. There was a certain craft to weaving all sorts of linked lists back and forth all the time and maintaining invariants that looking at my old code makes me a little nostalgic for, but I can't say I really miss it much.
