How to find out element position in slice?

Question

How does one determine the position of an element present in slice?

I need something like the following:
type intSlice []int

func (slice intSlice) pos(value int) int {
    for p, v := range slice {
        if (v == value) {
            return p
        }
    }
    return -1
}

If you happen to have a byte slice, there is bytes.IndexByte. You could write a function; func indexOf(element string, data []string) (int) { for k, v := range data { if element == v { return k } } return -1 //not found. } This returns the index of a character/string if it matches the element. If its not found, returns a -1.
