I meant it in the form of the simpler being better hypothesis. I am 
arguing that a simpler language often leads to complex code.

CorePy, PyCuda, PyOpenCL, etc. are not part of Python. They are 
extensions, and are not written in Python. Heck, C++ Boost is listed as 
a prerequisite for PyCuda.

The very existence of those shows that Python itself is not powerful enough.

Secondly, use of them does not make Python a simple language.

And thirdly, any language can have extension libraries and processors.
