An analogy: The language C is an O-O language because the following is both standard conforming and consistent with ADT views of C: Convert a void* to a struct that has a vtbl-Pointer that points to another struct (equally convertible from void*) that has a function pointer. Everything is type checked. This construct allows everything one needs in O-O programming. The programs following this view exhibit a view of C as a language whose structs obviously create inheritable O-O types that have operations, all in the sense of perfect ADTs. C is clearly an O-O language, then, since you can observe the behavior of such programs to be O-O. This style of argument will challenge other views of C in the style of a provocation that requires much work to set straight. Maybe the time is better spent on outlining the addition of abstract scalar types to Ada?
