    1 Oh, I had not noticed that 'CoxeterMatrixGroup' were acting on plain vectors with '*'. As you mention this is very ambiguous. For a Weyl group this is even worst: is the vector interpreted as in the span of the (co)roots? of the (co)weights? in the ambient space?

    33For now, I'd rather keep the notations as explicit as possible (in particular, it's easier to document a method `.action` than an overloaded operator). And leave us room in the future to overload '*', either by default, or upon explicit request from the user.
