--- Comment #2 from RazvanN <razvan.nitu1305 at gmail.com> ---
This is not a bug. The alias parameter can be seen as a pointer that is stored
inside the declaring struct. Since fun is static it should have no context
pointer, therefore it cannot access the alias parameter.

Yes, because your opCall is static and cannot access anything in B's context.
If you declare `A()` as static you will end up with the same error message.
