In stdtypes.rst, x.numbits should be listed in the table under
"Bit-string Operations on Integer Types" and not in the table of
operations supported by all numeric types.
> (1) the number of bits should be computed first directly using C
> arithmetic, and only recomputed using PyLong arithmetic if the C
> computations overflow.
+1
> (4) I quite like the idea of having numbits be a property rather than a
> method---might still be worth considering?
I'm not against.
