I dunno... is __new__ really more magic than having a __call__ method that magically copies the instance you call it on? That certainly breaks my expectations. Django doesn't shy away from "magic" in other areas where it makes for a usable API. The things that happen to model and form fields certainly violate the initial expectations of a Python programmer; but it turns out that most people are happy to write readable models and don't care what's happening under the hood, and those who do care can learn a little something about metaclasses. Seems to me that __new__ is a relatively beautiful solution to a thorny problem: it lets people use class views in all the same ways they use function views while maintaining thread-safety, it maintains the "callable that returns HttpResponse" contract, and most people won't ever see or care about the "magic" that makes it work. +1 for __new__.
