          **Warning:
          This method returns a clone of original value, modifying the returned value does not change the actual value in
          the map. One should put modified value back to make changes visible to all nodes.**

              >>> value.update_some_property()
              >>> map.put(key,value)
  
          **Warning 2: This method uses __hash__ and __eq__ methods of binary form of the key, not the actual implementations
          of __hash__ and __eq__ defined in key's class.**
