go slice cut (if slice has pointers)

If a Slice has pointers, It will result in the memeory leak, if we didn't nil the pointers. This snippet is used to do it.

	// Snippet: truncates the given slice 
	// a, array to be sliced 
	// i, starting index of the array 
	// j, ending index of the array 
  copy(a[i:], a[j:])
  for k, n := len(a)-j+i, len(a); k < n; k++ {
	  a[k] = nil // or the zero value of T
  a = a[:len(a)-j+i]
