While not an user of numpy, I feel legitimate to give my feedback as a
person with a scientific background.
I personally have always felt the lack of a binary operator expressing
non-commutative multiplication.
It could be used for matrices, but also for functions composition and
other more abstract things. I think a single new operator is all is
needed.
