Well, as far as I understand, that implementation would need to overcome the Generic Dilemma as described by Russ Cox: http://research.swtch.com/generic http://

  Option #3 is unfairly presented. There is no reason a language couldn't implicitly box every type, but automatically create efficient specializations for (some of) the types actually used. You can have your cake and eat it too. Of course, it's not easy to write such static optimizations. But it is, in principle, possible, and the sort of thing you only need write once.

  In a sense, they went for #3 (auto-boxing) without the syntactic sugar. Casting int to interface {} has a similar overhead to boxing in Java.
