Comment (by ncohen):
> The output is fine, it prints 1.0 in `p.show()`. Did you actually try
it?
I did not. I thought that it was one of the things you were leaving for
later, while you indeed say the opposite in your message. Hadn't noticed
that part.
> Also, right now the coefficients aren't converted into the base ring
unless the coercion framework requires it. This is something that should
be fixed as well, so coefficients always live in the respective base ring.
But thats another thing for later when the backends report their base
ring.
>
> With a stand-alone `Sum` function you can't do the empty sum - what
would be its parent?
It used to return None, and I lived fine with it.
Could you please answer my question about sum to p.sum ?
