I'm not sure I want to commit to writing something like that, since I
can't immediately visualize how much work it would be.  How much of a
Scheme number system should we assume in order to write a good example
of this concept?  Would it be sufficient to provide C versions of
nan-quiet?, nan-negative?, etc., operating on doubles?  This would be
fairly easy to wrap, I suppose, although my only FFI experience has
been with Chibi.
