Probably Go's developers would have never imagined to do numerical operations with their language. Only middlewares are in their sights. I'm impressed by Go's selector expressions and anonymous fields. They are what D's overload sets and opDot/alias this aimed to. But I love implicit casts with alias this at the same time. I withhold to say which is better, Go's interfaced pointers or D's value-struct/reference-class. On this point, both Go and D would have pros and cons. p.s. If both D and Go come to be major language, There will be many disputes like fray between users of Python / Ruby / Perl.
