Comment (by stumpc5):
> Also, instead of `act`, IIRC there is a method, which I believe is
`_act_on_` (not to be confused with `_acted_upon_`), that automatically
gets checked by the coercion framework. So it gives you `w * la`
essentially for free.
Done, I must admit that I like that way of having an element w in W act on
vectors, while I am nervous about this implicitness in the construction
that will likely result in bugs.

missing sentence?
