>The story is that generics for Go is an ongoing research project for the team.

I don't see that in real life. That's just a "shut up" story employed like 4 years ago. If it's an "ongoing research" project, where's any researchy output?

"Python 3000" was once a research project and had tons of proposals and research done on various features. Closures in Java were researched, and there were implementations tested. ES6 was an ongoing effort to add features to Javascript, and there have been test implementations, shims, etc before it's out.

All languages that wanted to add a feature had attempts by various key developers to add these to them, proposals, papers, testing, requests for comments, etc. Where are those regarding Go and generics?
