Numpy arrays do indeed support the @-operator for matrix multiplication.
In fact, one of the common design questions when adding the @-operator to Python was "why do this, when it's not used anywhere in the core language or standard library?" - and the answer was "because it's important for Numpy and the numerical user community".
(and finally, adding __matmul__ and __rmatmul__ is entirely backwards compatible; you can use objects with those methods on Python 3.4 - it's only `A @ B` which is a syntax error)
