Matrix mul infix

gistfile1.py

from functools import partial

class Infix(object):
    def __init__(self, func):
        self.func = func
    def __or__(self, other):
        return self.func(other)
    def __ror__(self, other):
        return Infix(partial(self.func, other))
    def __call__(self, v1, v2):
        return self.func(v1, v2)
        
@Infix
def mul(a,b):
  return mtimes(a,b)
  
from casadi import *

A = MX.sym("A",2,2)
b = MX.sym("b",2)

print A |mul| b

Isn't there a Python syntax for matrix multiplication already:

A @ b
