# reducing with a single polynomial list gives just the polynomial back
reduce(+, [p1])
p1
Doesn't this just work? It does for me.
# reducing with an empty list gives back the 0 polynomial

If you ensure that the array is correctly typed (eg: Poly[] ), you get:
To get an empty list of polynomials, you can type `Poly[]`. I wouldn't
recommend changing the behavior of the built in reduce function though,
that would definitely be confusing for anyone else who later wants to work
with your module (and who will reasonably expect Base.reduce to return a
