Python 3.5 shows @ as matrix multiplication. How to use it?

I am trying to figure out how to use matrix multiplication, operator @ in Python, listed in https://docs.python.org/3/reference/expressions.html, but I can´t find any example or make it work with lists.

How to use it?

Currently no builtin type uses the @ operator. You can define your own types to implement it by the __matmul__ magic word. Here is a basic example:

class Mx:
  def __matmul__(self, other):
    return "matmul {0} {1}".format(self, other)

print(Mx() @ 0)
