In the following example, ++x calls opUnary while x++ is performed on x
directly:

struct X
{
    int x;
    alias x this;

    typeof(this) opUnary (string operator) ()
    {
        writeln ("operator called");
        return this;
    }
}
unittest
{    
    X x;
    ++x; //operator called
    auto y = x++; //BUG! (alias this used. returns int)
}
