I'd say NaNs and unordered comparisons. In other words, it should
support the same semantics as float, double and real do.
If you've got the time and interest, adding all the functions in
std.math would be great!
I'm not sure I can sign up for ALL of std.math. I'm sure I'll need
help. I can do roots, powers and transcendental functions, though.
Maybe not very efficiently (power series).
(If very high precision numbers are questionable, how valuable are
high precision sine and cosine??)

Would be great if we could enlist Don's help. Don? :o)
In only slightly related news, the "new, new" Phobos2 offers custom
floating-point numbers, see
http://erdani.dreamhosters.com/d/web/phobos/std_numeric.html
They aren't infinite precision (which makes their utility orthogonal on
bigfloat's), but they allow fine tweaking of floating point storage.
Want to cram floats in 16 or 24 bits? Care about numbers in [0, 1) at
maximum precision? Give CustomFloat a shot.
