/**
 * Returns a range with no lower bound up to the given endpoint, which may be either inclusive
 * (closed) or exclusive (open).
 *
 * @since 14.0
 */
public static <C extends Comparable<?>> Range<C> upTo(C endpoint, BoundType boundType) {
 switch (boundType) {
  case OPEN:
   return lessThan(endpoint);
  case CLOSED:
   return atMost(endpoint);
  default:
   throw new AssertionError();
 }
