Qualifying that the right operand's type must be a *strict* subclass for the reflected method to take precedence avoids an edge case / counter-example when the types are actually equal.

    >>> class A:
    ...     def __add__(self, other):
    ...         print(1)
    ...     def __radd__(self, other):
    ...         print(2)
    ...
    >>> A() + A()
    1
    >>> issubclass(A, A)
    True
