This kind of wigs me out too.  For example, do the set and map data
structures depend on this total order property?  What happens when I
stick in a data structure which contains some floats somewhere in it,
and some of those floats are nan's?  Does the data structure continue to
work at all?  It totally wigs me out.

I wish there was some sensible way around it.  Probably the thing I
would like best is for calculations that produce nans to throw
exceptions.  But from what I've heard so far, this doesn't appear to be
possible.  Oh well.
