I think it's reasonable to expose NumericVar and the supporting function
prototypes in, say, numeric_internal.h; normal applications that just
want to operate on numerics as today can just include numeric.h, and
continue to be at arms-length of the implementation details, while code
that wants to optimize operations further can use numeric_internal.h and
be very aware that they are subject to heavy breakage if we ever feel a
need to change the internal API.
