It's not a technical restriction, as I said, but it's what lists are *for*. Indeed, it *can't* be a technical restriction, because, as I said, by 'type' I wasn't referring to anything technical. A list might contain, for example, "things to process". That's a conceptual kind of thing, so the list is conceptually homogeneous, but technically speaking, the list might contain instances of any class (or built-in type). A good example of a tuple, OTOH, might be a database tuple, i.e. a row returned from an RDBMS. Even if all the tables columns are of the same type - say, strings - it doesn't mean that they are interchangeable. Their position has semantic significance - it means something.
