docs: Returns the list of values associated with the key. ``None`` if this map does not contain this key.
  
          **Warning:
          This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode
          and equals defined in the key's class.**
  
          **Warning-2:
          The list is NOT backed by the multimap, so changes to the map are list reflected in the collection, and
          vice-versa.**
  
          :param key: (object), the specified key.
          :return: (Sequence), the list of the values associated with the specified key.
