Hi. I am working on numpy in pypy. It would be much more challenging for 
me if you merged more code into the core of numpy, that means even more 
must be duplicated when using a different underlying ndarray 
If you are thinking of touching linalg/lapack_lite/blas_lite, I would 
prefer a simpler model that uses ndarray as a simple storage container, 
does not use cpython-specifc capi extentions with reference counting, 
and interfaces with python via cffi[0].
