A Piece of History

Sigh, its a long time since I've been working on this compiler. I started about five and a half years ago, after spending too much time on thinking about SAT solving and P?=NP, and decided I needed to think about something simple for change - I just puzzle 24 hrs a day, can't stop it. The development has been slow, due to much reading, intervening work, and after some medication, a series of psychoses, but ah well, it's getting there.
