We basically need this because some of the type conversions those guts need to do may need a BindingCallContext. We could probably do more optimization here to only generate the BindingCallContext bits if we will really need them, more or less based on our return type. But for now that doesn't seem worthwhile.

* Subclasses corresponding to particular callback interface types should
