build a language

Part of the language we built in my last (so far as I know) Educational Studies Program class ("Build a Language"). The first class (and third time I'd ever taught this particular class) didn't go too well, but the second one went really well and made a good ending.

This is just one of a series of impending "lasts" for me at MIT, I guess. Sigh. Don't know what I feel about that, but it's happening nonetheless!
