Sorry that I did not point these out initially.

+ clnum seems to be slower and for speed may be compiled to wrap gmp so
that it is just an additional layer between python and gmp .

+ gmpy is looking pretty unmaintained (dead) to me (newest update of
cvs 10 months ago).

+ boost indeed is a quite nice C++ library. However, I fear that I
would end up writing the python wrappers for operators (+ - * / min
max cmp etc.) myself. I would like to avoid this since these operators
should work correctly for any type (not just int and float) and I have
little experience with verifying such generic code. The problems
encountered in the mxNumber wrapper support this notion.
