I agree that it can be useful for the built-in array module to grow
signed/unsigned 64 bit numbers.

Numpy supports signed/unsigned 64 bit numbers too, so that may be
enough for you:
http://docs.scipy.org/doc/numpy/user/basics.types.html

Regarding 128-bit numbers you may have to support them manually, with
pairs of uint64, with numpy. They aren't much common yet.
(D language will have cent/ucent 128 bit integral numbers, but it's
not a common thing).
