John Meacham also told me that even if I get there, it wouldn't do
what I want (use it to support complex numbers).

Can you tell me what are the issues involved? From my naive view,
something like CDComplex (mapping to C double _Complex) wouldn't
be different than what's done for other basic types. Why am I
wrong?

Thanks,
