them the caveat of calling float(x) on any scalar they want to use
with the 'old' ones for now.
I remember being excited about your work on the new Polys, but since
I'm teaching with stock 1.3, I hadn't found them recently and just
forgot about them. Excellent.
One minor suggestion: I think it would be useful to have the new
polys have some form of pretty-printing like the old ones. It is
actually useful when working, to verify what one has at hand, to see
an expanded printout like the old ones do:
I thought about that, but decided it was best left to a derived class, say PrettyPoly ;) Overriding __repr__ and __str__ is an example where inheritance makes sense.
