Yep, CPython for now. If activestate supports the CPython C API, then 
supporting it will probably just be a matter of linkage.

Googling, it looks like PyPy is/was trying to grow some CPython C API 
compatibility, so hopefully we can squeeze it in at some point.

I had a look at numpy, and at least ndarray supports the new style 
buffer interface (which is pretty freaking complicated), so convertion 
is totally doable. I'll fold in support as soon as I can get dmd to stop 
stabbing me in the face.


just used your scons fork to build the pyd embedded unittests. works 
pretty nice
