The problem is that it would monkey with existing semantics for
broadcasting, and break with all the other arithmetic operators in
this regard. I can't see it ever being accepted for that reason.
Example:
In [514]: x
Out[514]:
array([[0, 1, 2],
[3, 4, 5],
[6, 7, 8]])
In [515]: y
Out[515]: array([0, 1, 2])
In [516]: x % y
Out[516]:
array([[0, 0, 0],
[0, 0, 1],
[0, 0, 0]])
