NUMERIC private methods?

Folks,

While noodling with some weighted statistics
<https://github.com/davidfetter/weighted_stats>, I noticed I was
having to jump through a lot of hoops because of all the private
methods in numeric.c, especially NumericVar.  Would there be some
major objection to exposing NumericVar as an opaque blob?

Cheers,
David.
