so the part preceded by ‘match’ is the preparation phase for matching.
Are you intending p0, p1 and p2 to be subpatterns rather than object
instantiations? That makes me a little twitchy; the difference between
what you wrote and:
match poly:
p0 = Point(x0, y0)
p1 = Point(x1, y1)
case Polygon(p0, p1, p2):

is very easy to miss.
