Re: arithmetic

Would it not make more sense to have 1/0, -1/0, and 0/0 print as something
which says infinity, -infinity, and undefined (e.g. #INF, #-INF, #UNDEF (I
know these aren't good choices, but you get the idea)).  There is still
nothing to prevent the imlementer from representing them internally as
1/0,-1/0, and 0/0 and having everything fall through nicely; readers and
printers just have to be a little cleverer.
