Replying to [comment:12 SimonKing]:
> However, I think it doesn't matter what Singular does. I will look up
the literature whether one really wants a ''right'' or ''left'' action...
I mean, something like "one has a left action on a variety, which gives
rise to a right action on the coordinate ring". I have to sort it out.
If this is the case, then it should be better implemented in the `__mul__`
method of polynomials, isn't it? Such as
{{{
sage: p*G.1*G.0==p*(G.1*G.0)
True
}}}
