Thing I want for caching in Django

get_or_set.py

class MyCacheBackendThing(Ellipsis):
    def get_or_set(self, key, timeout, setter):
        data = self.get(key, None)
        if data is None:
            data = setter
            if callable(data):
                data = data()
            self.set(key, data, timeout)
        return data

Welp, this is just a poor implementation of Django ticket #12982. Oh well.
