I have some questions:

1. Since in math, the operator is usually spelt "·" (the center dot,
     or "." but that's already reserved for methods and attributes in
     Python), why not try to use that instead of "@" (which in Python
     already identifies decorators) ?

I think the current feeling of the Python core team is against including non-ASCII characters in the
language's keywords or operators. Even if that were not so, I would still recommend against it
because it would be quite difficult to type. I don't know off-hand the key combination to do it on
my native system, and it would change from system to system.

That's a fair argument. How about using the degree symbol instead: "°" ?

(A ° B).T == B.T ° A.T

Your point is taken, though. I do find these smaller symbols more readable and similar to standard mathematical notation than an @ sign, which is as big or bigger than most uppercase characters. Unfortunately, ASCII leaves us few single-character options.
