   * similar but different from {@link Class#getGenericInterfaces()}. For example, {@code new
   * TypeToken<List<String>>() {}.getGenericInterfaces()} will return a list that contains {@code
   * new TypeToken<Iterable<String>>() {}}; while {@code List.class.getGenericInterfaces()} will
   * return an array that contains {@code Iterable<T>}, where the {@code T} is the type variable
