Comment (by mantepse):
Hi there!
I was just about to do what Nicolas suggest -- adding an optional argument
`coerce`, but I encountered some things that make me hesitate:
1. to be helpful for the casual user, it's default value would have to be
`True` - differently from what we have in `_from_dict`.
2. the docstring would then be something like
{{{
whether to try to coerce the result of applying `f` to the coefficient
ring.
}}}
which is a bit strange, given that we require `f` to be an
endofunction.
If you reassure me, I'll do it. I'm just not 100% sure myself.
