code: public static ConfigList fromIterable(Iterable<? extends Object> values,
              String originDescription) {
          return (ConfigList) fromAnyRef(values, originDescription);
      }
docs: See the fromAnyRef() documentation for details. This is a typesafe
  wrapper that only works on {@link java.lang.Iterable} and returns
  {@link ConfigList} rather than {@link ConfigValue}.
  
  @param values
  @param originDescription
  @return a new {@link ConfigList} value
