Well, could you elaborate a little on joining efforts? The effort I
was planning to invest in my package consists mainly of creating a
.cabal file plus some logistics to get tarballs to where they have to

I understand that you (and Wolfgang) are creating a library of type
level decimals for the purpose of constraining vector (list?) lengths.
After that I haven't been paying attention fully to the thread. Is the
goal to create a general-purpose library for type-level programming
and my module would fit into that grander scheme?

Or did you have something else in mind with joining efforts? E.g. help
reviewing your code or writing new code?
