Member predicate ObjectInternal :: functionAndOffset
Holds if the object function is called when this object is called and paramOffset
is the difference from the parameter position and the argument position.
For a normal function paramOffset is 0. For classes and bound-methods it is 1.
This is used to implement the CallableValue public API.
