Comment (by rws):
This is from comment 2 in #9769 by burcin:
> {{{
> sage: x = PolynomialRing(RR, 'x').gen()
> sage: sin(x)
> <boom>
> }}}
>
> The problem here is really coercion, but it should be copied to another
ticket (in the basic_arithmetic component):
> The `__call__()` function of RR[x] doesn't conform to the generic
definition. You should be able to give the parameters as a keyword
argument as well. This should be made to work:
>
> {{{
> sage: R.<x> = RR[]
> sage: (x^2+1)(x=5)
> 11
> }}}
