"Attributes of Objects" are essentially dictionaries. Access to elements of 
dictionaries is O(1), meaning: not depending on the length of the 
dictionary. (assuming there are no hash collisions)

You should try to compare performace with numeric indizes to Tuples instead 
of lists, cause tuples are invariant they may be faster.
