I got quite a bit of work done today, fixing several bugs in the typechecker. I need to really walk through all the code again and make sure I'm not making false assumptions - the gap between the system on paper and the system in code has grown rather sizeable. As confusing as deBruijn indices and explicit substitutions are, I'm kind of fond of their arcane mechanicalness.

Went to lunch with teki and lars_chan, since the former is actually in town. Veracruz's burritos are really quite tasty with the sketchy-looking Heinz Taco Sauce they have available there. I wouldn't necessarily trust Heinz to make taco sauce, but, hey, it's pittsburgh.
