Neat!

I'm curious if you've looked at Core_kernel's Univ_map?  I believe it's
very similar in spirit, and I'm curious if there are any interesting
differences there:

Our type witnesses are a little interesting in that you can derive new
witnesses from old ones (e.g., if a equals a', and b equals b', then a * b
equals a' * b').  That said, I'm not sure that this is relevant for the
heterogenous map use case.
