From the book The Go Programming Language

To remove an element from the middle of a slice, preserving the order of the remaining elements, use copy to slide the higher-numbered elements down by one to fill the gap:

func remove(slice []int, i int) []int {
  copy(slice[i:], slice[i+1:])
  return slice[:len(slice)-1]
}
