Comment (by behackl):
Replying to [comment:9 vdelecroix]:
> It is not that trivial to fix. The thing is that you can not multiply by
`0` in `GL` and there are much more restriction in `SL`... So the action
should not go through a coercion.
I'd propose to implement `_lmul_` and `_rmul_`; I agree that embedding via
coercion is not practicable.
Regarding the `base_ring` and the fact that there might not be one: yes,
that has to be taken care of. I haven't thought of that because I was
implementing the original version with #20086 in mind. I can't really
contribute to the discussion which approach is the most suitable; it just
has to be consistent.
