-------------------------------------+-------------------------------------
Evaluating of a polynomial (from a polynomial ring) on an element of `SR`
calls a generic implementation of Horner evaluation, so that the result is
in (a kind of) Horner form:
{{{
sage: pol = QQ['x'](range(10))
sage: pol(x)
((((((((9*x + 8)*x + 7)*x + 6)*x + 5)*x + 4)*x + 3)*x + 2)*x + 1)*x
}}}
This is probably not what users expect. Additionally, the conversion could
be much more efficient.
