Named return values in go

Avoid needlessly instantiating return variables!

Instead of:

// Sum each integer in a string of only integers
func countLetterA(input string) int {
  v := 0
  for _, s := range input {
		if s == 'a' {
			v++
		}
  }
  return v

Do:

func countLetterA(input string) (v int) {
  for _, s := range input {
		if s == 'a' {
			v++
		}
  }
  return
