No need to wait for this. :-)  I don't really expect to get much speed gain
at all in normal, low-precision (= precisions less than 100 digits, say)
use.  Even doubling the speed would be way too much to hope for here.

The only real gain from a decimal integer coefficient would be fixing
the asymptotics for high-precision calculations.
