function checkIterable (type: StorageEntryTypeLatest): boolean {
  const def = type.isMap
    ? getTypeDef(type.asMap.key.toString())
    : type.isDoubleMap
      ? getTypeDef(type.asDoubleMap.key2.toString())

  // in the case of Option<type> keys, we don't allow map iteration, in this case
  // we would have option for the iterable and then option for the key value
  return !!def && def.info !== TypeDefInfo.Option;
