This also breaks immutable class objects, which is really bad:

void spam(ref int x) 
{
    x++;
}

class Foo 
{
    int x = 5;
    void bar() immutable {
        spam(x);
    }
}
void main() 
{
    auto b = new immutable(Foo);

    //~ b.x = 10;   // uncommment for error
    assert(b.x == 5);
    b.bar();
    assert(b.x == 6);
}

If you uncomment b.x = 10, you will of course get an error. Maybe raise this
bug to a higher priority?
