Comment (by nthiery):
> Question: Why is that method not overridden for the different
realisations of `MacdonaldPolynomials`?
Because the coercions are registered explicitly during the initialization
of Sym / macdonald polynomials. This is better because it leaves maximal
freedom to the coercion model (e.g. the coercion model can't do
transitivity with _coerce_map_from).
Cheers,
Nicolas
