So, the inference tries to determine `E`, infers it to be `int` and then substitutes that into the return type to make it `[]int`. `MySlice` is assignable to `[]int`, as they have the same underlying type and the latter is not a defined type. So, you can pass `MySlice` to `Double[int]` just fine. You have to actually mention a separate type for the compiler to emit one, otherwise it will just do what it told you: https://go.dev/play/p/l1ochwkavNN > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/golang-nuts/f102326a-5cf6-40dc-bd57-268016284aecn%40googlegroups.com > <https://groups.google.com/d/msgid/golang-nuts/f102326a-5cf6-40dc-bd57-268016284aecn%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
