Member predicate PythonFunctionObjectInternal :: calleeAndOffset

Holds if the function scope 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. Used by points-to to help determine flow from arguments to parameters.
