but I think that puts the emphasis on the wrong thing. If (and that's a big
if) we did something like this, it should be a pair of methods __op__ and
the right-hand version __rop__ which get called on the *operands*, not the
operator/function object:

def __op__(self, other, symbol)

I thought the operator should have a say in how it operates, e.g. the operater `dot` could call __dot__ in its operands.

class Vector:
    def _dot(self, other):
        return sum([i * j for i, j in zip(self, other)])

class dot(operator):
    def __infix__(self, left, right):
        return left._dot(left, right)

>>>Vector([1,2,3]) dot Vector([3,4,5])

Making the declaration and import of operators more explicit than the `def __op__(self, other, symbol)` version. We could put [/, *, ., //, etc...] in __builtins__
