           Summary: [Regression] opCast of a struct or union is called in
                    nonsensical circumstances
           Product: D

          Severity: major

This used to work.  But now, it's broken the bit array/pointer types in my utility library.

----------
struct Qwert {
    Yuiop opCast() {
        return Yuiop.init;
    }
}

struct Yuiop {
    Qwert asdfg() {
        return Qwert.init;
    }

    void hjkl() {
        Qwert zxcvb = asdfg();  // line 13
    }
}
----------
opCast_struct.d(13): Error: cannot implicitly convert expression
(((this.asdfg)().opCast)()) of type Yuiop to Qwert
----------

There's absolutely no reason that it should be trying to call Qwert.opCast. adsfg() is already of type qwert; even if it wasn't, this wouldn't make sense since "Overloading the cast operator does not affect implicit casts, it only applies to explicit casts."

If Qwert.opCast is removed, the code compiles without error.
