interface I { }

class A : I {
    int x;
    alias x this;
    void f() {
        auto i = cast(I) this;  // ouch
    }
}

Should work but doesn't:
Error: e2ir: cannot cast this.x of type int to type hello.I

The cast can be outside -- still the same error:

void main() {
    auto a = new A;
    auto i = cast(I) a;  // ouch
}
