I have not been told that for several years, and I am pretty sure you 
will not find any such thing in the current docs. I consider it pretty 
much obsolete, as the differences that flowed from that idea are gone. 
In Python 3, tuples have all the non-mutating sequence methods that list 
does. The situation was much different in 1.4.
