There is a recent blog post about when to use generics in go:

https://go.dev/blog/when-generics

Interesting is their paragraph "For type parameters, prefer functions to methods", which was our discussion at the last J3 meeting also (whether to allow type-bound procedures, i.e., methods), it seems the direction was to not allow type-bound procedures at least for now. Consistent with Go, so I was happy to read that.

Also, as a reminder, here is our document that compares various languages an an example with generics, Go is the first one:
