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) p

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.
