docs: // SetInt sets the field value to the passed integer.  This is a convenience
  // function since it is fairly common to perform some arithemetic with small
  // native integers.
  //
  // The field value is returned to support chaining.  This enables syntax such
  // as f := new(fieldVal).SetInt(2).Mul(f2) so that f = 2 * f2.
