Well, that, and people are busy, and how to do some things depends
on which of MPTC, Fundeps, AT, etc. make it into Haskell'.

I mean, it's obvious it needs to be dealt with, and most everybody
agrees on the general shape of things, the big concerns are with how
much extra stuff beyond the basics should be defined by Haskell' rather
than just enabled by a better numeric hierarchy.
