After hacking Rust, I got the feeling that generics are hard. They are so hard that a language should consider them from the beginning to fully take advantage of them. That might be the reason why the Go team says generics are hard to implement in the current Go type system. They can also choose either C++-like code generation based on templates, or external code generating tools, but both are not perfect in my opinion.
