--- Comment #1 from Basile-z <b2.temp@gmx.com> ---
This is more subtle:

---
module runnable;

import std.stdio;

extern(C++) interface Foo
{
    void foo();
}

extern(C++) interface Bar
{
    void bar();
}

extern(C++) class C1 : Foo
{
    void foo(){writeln("do I look like a Bar !!");}
}

void main(string[] args)
{
    (cast(Bar) new C1).bar();
}
---

With the C++ compat this is clearly not @safe. The fix would have to check carefully these details.

Yeah, should work only for proper D interfaces.
