Comment (by tscrim):
Okay, then we need to get back on #15303 as setting up `_coerce_map_from_`
can be somewhat painful for things with multiple realizations (ex.
symmetric functions). Also, do you think it's worthwhile documenting this
somewhere and if so, where? The coercion thematic tutorial(s) or somewhere
in `coerce.pyx`?
