PyPy support

[GoogleCodeExporter]

PyPy 1.3 has (alpha) support for CPython extension modules. It would be nice if 
gmpy ran in PyPy.

I read that in the announcement, too. I will give it a try.

As a test, I wrote a very small RPython module to access a simple function in 
the mpfr library. It was faster, but the translation (compile) step took a long 
time and there doesn't appear to be a way to develop an RPython module without 
including it directly into PyPy. This would probably cause licensing issues, 
too. The cpyext (sp?) approach won't work at all unless I remove many of the 
optimizations I've added and it supposedly adds quite a bit of overhead.

Closing. Not practical at the moment.

How hard would it be to use CFFI?  That would enable PyPy integration, as an 
alternative to using the CPython support of PyPy.

Someone has started a CFFI wrapper. See
