This was a pain point. I had hacked the "names" of symbols into the
throw/catch representation, never appreciating how badly I was screwing
up my understanding of LiSP. The symbols are supposed to evaluate
to something. When they're self-evaluating expressions (strings and
numbers), those become the keys in the block stack that matter. Getting
SEE's right, whether they're quoted or not, was really signficant.
This is cool. Now, on to rewind/protect!
