I hadn't thought about that, but I guess I can add that to intpol.lisp.
However, on review of the code, there are some issues with
coerce-bfloat-fun. I'll have to fix those. And it would be best if we
didn't have to duplicate coerce-float-fun and friends. I'll have to
think of some way to have them work with both float and bfloat numbers.
