We should not exaggerate the importance of this.  The aim of Emacs
Lisp is to "get the job done", not to be maximally elegant.

Adding real bignums probably would not be much more work than that.
So IF we decide to do work in that area, let's add real bignums.
GNU MP does the hard part.

However, I'd rather prioritize progress in computing horizontal
alignment and widths with variable-width fonts.  That is something
we really need.
