I know this is an old post, just thought to share possible work around.
Idea is basically return a func that will return multiple values. I'm not
sure how much performance overhead this will create and it's a little bit
ugly, but works as intended.
func f(c chan func() (int, string)) {
c <- (func() (int, string) { return 0, "s" })
}
func main() {
c := make(chan func() (int, string))
go f(c)
y, z := (<-c)()
fmt.Println(y)
fmt.Println(z)
}
