Example
- They are idiomatic
// The (int, int) in this function signature shows that the function returns 2
// ints.
vals := func()(int, int) {
return 3, 7
}
// Here we use the 2 different return values from the call with multiple
// assignment.
a, b := vals()
fmt.Println(a)
fmt.Println(b)
// If you only want a subset of the returned values, use the blank identifier
// _.
_, c := vals()
fmt.Println(c)
