Yep -- "time tuples" have also become pseudo-tuples (each element can be
accessed by name as well as by index) a while ago, and I believe there's
one more example besides stats and times (but I can't recall which one).

Perhaps, if the tuple type _in general_ allowed naming the items in a
smooth way, that might help users see a tuple as "a kind of
``struct''... which also happens to be immutable".  There are a few such
"supertuples" (with item-naming) in the cookbook, but I wonder if it
might not be worth having such functionality in the standard library
(for this clarification as well as, sometimes, helping the readability
of some user code).
