If you feel a real strong need for generics, for something like a "sort by property of my custom type... do it for n types", then it's now trivial to generate that.
You can code like you have the features the core doesn't support, whilst having the succinctness, performance and maintainability that the language delivers.
I've coded Go almost daily for 2+ years and only a couple of times had the urge/need for generics... I dunno, maybe I'm the exception here.
The proposal (the implementation is pretty much this) is here: https://docs.google.com/a/golang.org/document/d/1V03LUfjSADD...
