Both forms work but they mean two different things. Print(s []Stringer) takes a slice of the type Stringer. Print[T Stringer](s []T) takes a slice of some type T, where T implements Stringer. For example, if MyInt implements Stringer, and I have a []MyInt, then I can call Print[T Stringer](s []T) but I can't call Print(s []Stringer), because a []Stringer is not a []MyInt.
