dynamic rest client concept (abuse python's getattr and getitem)

dynamic_rest_client.py

        self.m4ngl3 = dict(uri=uri, api=api) # prevent name collisions (with actual members called "uri" or "api", endpoints of these names couldn't be used - we can probably live without ones named "m4ngl3")

    def __getitem__(self, name):
        api, uri = self.m4ngl3["api"], self.m4ngl3["uri"]
        key = api.canonize(uri, name)
