I'd recommend to have two types of callback functions.
One callback function takes no argument and returns nothing (= void).
The other takes some arguments and returns something.
So that we can see generated code that handles arguments and return value.

could you rename this type more descriptive?
e.g. VoidExperimentalCallbackFunction, ExperimentalClosure
