Yeah, looks like calc-math.el:math-* could work.  It's all ELisp and
could use some C love, especially if 64-bit is native.  So Lars can use
the math-* functions to store and retrieve large numbers (they fall back
to native ELisp numbers) and he'll need a special range-memq to work
with the math-* bignums in a range.
