Hi Niles,
Why not modifying the comparison codes for Callable function ring?
> If you do *not* want these things to compare equal then you should break
the coercion. That might be reasonable. Conversion can still exist.
Currently you can do:
> {{{
> sage: f+y^2
> x |--> x*y + y^2
> }}}
> without coercion but with conversion, this would need to be:
> {{{
> sage: f+cSR(y^2)
> x |--> x*y + y^2
> }}}
> which does not seem unreasonable to me.
I definitely would like to be able to do `f+1` without an error!
