"Objects are a poor man's closure" example

Here you have two closures with shared state. Unsure whether that qualifies…

Why wouldn’t it? createCounter could return one closure to increment c, but this example shows how one can group closures together to create an object with shared state.

Yea, but now you have a “group”.

Perhaps you were thinking about something like (Go Playground):

func NewCounter() func(int) int {
	var coutnter int

	return func(x int) int {
		coutnter += x

		return coutnter
	}
}

func main() {
	c := NewCounter()

	fmt.Println("+1:", c(1))
	fmt.Println("+2:", c(2))
	fmt.Println("-1:", c(-1))
}
