   The main difference between lists and tuples is not mutability but
usage: lists are for a (unknown) number of similar items (a list of
messages, e.g.), tuples are for a (known) number of different items at
fixed positions (an address is a tuple of (country, city, street
address), for example).

           Programmers don't die, they just GOSUB without RETURN.
