Indeed, and this can be fixed straightforward. However, there is (once
again ...) a slight inconvenience: there are superfluous parentheses in,
e.g.
{{{
sage: P.<x> = ZZ[]
sage: P(4).nth_root(3)
Traceback (most recent call last):
...
ValueError: (4)^(1/3) does not lie in ...
}}}
or
{{{
sage: x.nth_root(3)
Traceback (most recent call last):
...
ValueError: (x)^(1/3) does not lie in ...
}}}
Should we live with that? Fixing it would require querying something like
`self.is_constant()` and `self in self.parent().gens()` or so.
