No it is a defintion because it states this can be done for every possible case, even cases you have no idea about. > Note that I have proved elsewhere on this thread that any real use case for > tuple.index will involve an operation to explicitly use an index different > from the one obtained by the call to tuple.index().

Adding the index method to tuples is not adding a feature. It is removing a limitation. Writing an index function in python that works with whatever sequence is dead easy. So if the python core implementation only works with a specific sequence that is putting on unnecessary limitations. >> Of course it also limits the language to what the developers can >> think off. > > Initially, yes, but if enough use cases exist for a feature that the > developers didn't think of, it will be implemented. Which means your language will not be that usefull for a number of things until you have frustrated enough people. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
