I think the consensus is we want that, it's just a matter of someone
doing the job of making it happen.

The design should IMO be discussed up front, because we want not only
to be able to use bignums and arbitrary-precision floating-point
numbers in C, but also in Lisp.  How exactly to expose them to Lisp is
something we should talk about, I think.

Thanks.
