Well, I'd argue __super is not specifically related to C++/CLI.

After all, there's still __stdcall, __declspec, __pragma etc.

In fact, some argue __super is especially useful with multiple
inheritance where the appropriate base class is selected based
on context.
Typically, however, you wouldn't use __super to refer to
an interface.

Anyway, I fail to see any case where you couldn't use
the (injected) base class name instead of using __super.
