PEP 465 – Dedicated infix operators for matrix multiplication and matrix power

I agree. I wish python had the capability to infix functions. Maybe the topic for a new PEP ?

This is this[1] workaround.

I wonder if a whole set of infix matrix operations could be added to reduce the need to load numpy for simple tasks.

Yes, but making it part of the language would bring clear error messages in case of misuse, and would allow the use of a different token, e.g. ":", as in smalltalk
