[Twisted-Python] jelly and instances

doc says: Instance: s is an instance of UserString.UserString, with a __dict__ {'data': 'hello'}:: [\"UserString.UserString\", ['dictionary', ['data', 'hello']]] There is no test for instances. To be precise, no test ever enters jelly._unjelly_instance() I also cannot find any place in jelly.py where an Instance would be jellied. There is instance_atom = 'instance' but instance_atom is not used anywhere. Is this outdated code? If not, could you please give me a code example using this? -- Wolfgang
