After sleeping on it, I see that you were right all along & I was
wrong. I was focusing on the polynomial (0), but that is not in
canonical form. The canonical form for the zero polynomial is (empty).
I will remove the error-check, unless you want to do it yourself.

Oh, yes... and I guess that's been a concern of yours all through this thread.
If I understand the wikipedia treatment correctly, this is an
ambiguity where different authors treat polynomial degree differently.
And, I guess, negative infinity for the degree of zero polynomials
would require a different implementation:
pdegree=: {{(<:%*) +/ +./\. 0 ~: y}}
pdegree 1 2 1
2
pdegree 5
0
pdegree 0

I suppose you could go with a zero polynomial having negative infinite

That is what henry suggested. I agree that it doesn't change the answer to
the question of whether i.0 is a polynomial.
