There is a big difference here. The draft is about adding generics to the Go stdlib, not about if it's possible. Is it even possible? Yeah, there are some implementation (e.g. https://github.com/cheekybits/genny ). So Go is not "far behind" C, which also does not have generics (or did I miss something in C11/C17?).

You missed, C17 introduced lightweight generics via _Generic and C2X plans to extend it further.

can i say T : SomeConstraint ?

in C++ ? sure template void F(T p) { ... } or just void F(SomeConstraint auto p) { ... } like this for instance: https://gcc.godbolt.org/z/hPM38T
