Very good introduction to generics in Go.

4:58 I have two questions. First, how package foo has access to structure `prov` defined in the package provider? I was thinking that type name must starts with capital letter to be exported?

Second is about method `func (p *prov) ID provider.ID`. It now has code `return ID` and I would expected something like `return p.ID`.

I think the example is too advanced for introduction to generics in Go. Slice or sort operations with multiple types (int, float, ...) would be more understandble.
