Oops, I meant to try the code without param. That's a relic earlier
hacking with it. As it stands I was able to feed the geocoder to it
and it did run.

I tried tail recursion first. I had trouble getting it balanced. The
biggest problem I have with using locals is I can't figure out a
simple way to infer quotations when I'm out of balance. The times I
need locals are times when unbalanced branches are most likely to come
up.
