Another big hole in my thesis has shown up and been patched. Turns out the proof of spine application injectivity was pretty much totally bogus. I needed to toss a whole bunch of grungy technical facts about contexts in a dependent type theory at it to get it to work. But it does seem to now. I really like the approach of treating spines as just another data structure and head-spine application as a totally syntactic recursively defined function. I hope the technique stands up to the definition of strictness.

Also Tartan-day, the last one of the semester. My last-minute plea for last-Tartan comics seems to have worked a little. Getting some late thugbot, suburbanites, fence, and extra-large curtis. I may not have to use the filler column after all. We'll see.
