Does this support unordered output?

I just spotted in https://pkg.go.dev/cmd/go/internal/test:

Here is another example where the ordering of the output is ignored:

	func ExamplePerm() {
		for _, value := range Perm(4) {
			fmt.Println(value)
		}

		// Unordered output: 4
		// 2
		// 1
		// 3
		// 0
	}

And we may want to make that a valid case, too?

Yes, it supports all example capabilities because it uses stdlib to get example info, see https://github.com/maratori/testableexamples/blob/main/pkg/testableexamples/testableexamples.go#L25
