I can't tell if you want generics or not? I've been thinking about the topic for a while and sort of think Go doesn't need em. It's less a technical reason but more a cultural reason. The language shipped without them as a feature. So why deprecate that feature and make lite-version of Java/C#.

A decent chunk of new Go developers are former Java developers. (I'm not being disparaging here, I came over to Go from Java!) I think the idea of "accept interfaces, return structs" doesn't sink in very well and isn't as readily apparent as it could be.

When I have a function that takes a struct, and I need it to take a different struct for the same argument due to whatever, that to me screams "make an interface", but I hadn't been programming Java very long before my team started using Go - I've now been writing Go professionally longer than I have Java.
