For the time being it seems that the golang authors are set against generics. Phew! And while there have not been any new arguments only squeaky wheels... If the golang authors ever implement generics I'll slip back to erlang.
"Yes it's annoying to rewrite boilerplate"
If you believe that statement as the argument for generics then turn in you diploma and clean out your desk. First of all how much code could that be? Second, that's what you get paid for? Added complexity and time in the compiler for what? Just go watch the intro ocaml video.
