To my eyes, this sound like the most fatuous piece of O'Woe (Order of Worshipful Over Engineers) rubbish I've seen in a long time.
Considering that both Python and Common Lisp employ docstrings for the users of a class, I don't think "rubbish" would be an accurate term to describe my aspiration. I was merely asking if it was possible since a series of if/elsif/else constructs would have been less than elegant.
