Test cases:

void test()
{
    struct X
    {
        Object get() immutable { return null; }
        alias get this;
    }
    immutable(X) x;
    Object y;
    static assert( is(typeof(1?x:y) == Object));        // fails
    static assert(!is(typeof(1?x:y) == const(Object))); // fails

    struct A
    {
        int[] get() immutable { return null; }
        alias get this;
    }
    immutable(A) a;
    int[] b;
    static assert( is(typeof(1?a:b) == int[]));         // fails
    static assert(!is(typeof(1?a:b) == const(int[])));  // fails
}
