Modern Static Typing: Less Code, Better Code

“Consider:

class Artist:
    def draw(self):
        print "Sketch!"

class Gunslinger:
    def draw(self):
        print "Bang!"

for obj in [Artist(), Gunslinger()]:
    obj.draw()

Artist.draw and Gunslinger.draw are clearly not even conceptually related, and our Artist has wandered unwittingly into a gunfight. I considered this problem to be fairly unimportant from a practical standpoint, because it usually doesn’t happen very often.”
