CPP11 — No conversion defined from a B_var to an A_ptr

  • Summary:

    Summary: I was writing some C++ code and noticed that the following doesn"t work:

    // IDL

    interface A {
    };

    interface B : A {
    };

    // C++

    B_var bv = get_b_from_somewhere();
    A_var av = A::_duplicate(bv);

    because there is no conversion defined from a B_var to an A_ptr. Is
    there a way that this could be added to the language binding without
    ambiguity problems?
