Comment (by nthiery):
Replying to [comment:10 SimonKing]:
> Or, even more informative: Return a pair `(op, method)`, such that
> - `op` is the operator (either as in `operator.contains`,
`operator.mul`, `operator.and`, or a parent/element method such as
`an_element`), and
> - `method` is an abstract parent/element method that has to be
implemented for `op` (i.e., `__contains__`, `_mul_`, or `_an_element`)
Possibly so indeed. Although this would be duplicating a bit the job
of `required_methods`. I am not sure we want to put a specific
emphasis on the methods related to an operation that adds structure
(e.g. '+') or that does not (e.g. '-').
Speaking of which: see #16363.
