Thanks for the link. I read it and my understanding of it is that they are doing  templates + strong concepts (using C++ terminology), which we have determined in the Generics subgroup is the way to go. The Go proposal shows on an example how it differs from C++ templates.

They specifically show that the constraint causes the compiler to check both the user code (instantiation) and the library code (generics code). That's called the strong concept in C++.

Is anybody interested in having a video call next week to make some more progress on generics?

Here is our current status:
