That sounds like a great option. Candidate numero uno as of now. What
I have in mind right now should be pretty light weight, but it will
mostly be a regurgitation of code I've seen floating around. Some of
the code from the previous wiki link, type-level decimal numbers I saw
in an Oleg paper (I think), etc.

Would you be open to such code in your library? Anyone have a better
place for it?
