Note that I am not opposed to extra operators in python, and only mildly
opposed to a matrix multiplication operator in numpy; but let me lay out
the case against, for your consideration.
First of all, the use of matrix semantics relative to arrays semantics is
extremely rare; even in linear
This is awesome! Congrats!

Different people work on different code and have different experiences
here -- yours may or may be typical yours. Pauli did some quick checks
on scikit-learn nipy scipy, and found that in their test suites,
uses of np.dot and uses of elementwise-multiplication are ~equally

An important distinction between calling dot or @ is that matrix
multiplication is a domain where enormous effort has already been spent on
algorithms and building fast, scalable libraries. Yes einsum can call
these for some subset of calls but it's also trivial to set up a case where
it can't.

This id good for Numpyists but this will be another operator that good also
help in another contexts.
As a math user, I was first very skeptical but finally this is a good news
for non Numpyists too.
