Ackkkk I'm actually rewriting it currently to try and ameliorate the cruft that's crept in since the 2.0 rewrite. I want to say "But wait! If you read the code in a couple weeks it'll be so much better!"
Trust me, I'm sure I can improve my Python skills by reading the current version. I don't get a chance to use Python enough to shed the baggage of other languages to write Pythonic code, if that makes sense.
I haven't used Peewee in a project yet, but I've poked around with it. It's really nice, so thank you.
