The caller doesn't have to make any assumptions. It passes the 'self' pointer on the stack, since it knows that the callee wants that. But I see now that this can't work. Because the 'callee' expects the interface-pointer, not the class-pointer. And we can change that for pascal-callee's, but not for others. So it comes down on the same thing: this option can't work. I'll try option 1 as you and Jonas pointed out that shoudn't be a problem.
