You only need this workaround if you habe a class hierarchy where 
overloaded operators are
overridden in subclasses. This is a very narrow set of cases. 
Otherwise, implementing only the D2 way is sufficient. How often 
do you actually need to override operator behaviour in 
subclasses? I'm genuinely curious about use cases.
