Remember that Go vs D MQTT thing and how we wondered about dmd vs gdc?

That's fine - the man doesn't like OOP and that influences the design of 
his language. I also suspect he's not conversant with the various 
modularity-related aspects of Visitor, given the glibness of the answer.

And that all is fine. Walter and I also have various lacuna, and that 
does influence the design of D. The same goes about virtually all 
programming languages.
