Python may be the best base to compare things to as tuple assignment has been in there for years.Pythons choice is not a car/cdr approach but an exact match approach. so if t represents a tuple datum or a function returning a tuple: x = t then x is a tuple -- remembering that variables are all just references to objects implemented via keys in a dictionary, and: a , b , c = t or ( a , b , c ) = t is tuple assignment where now t is required to be a tuple of length 3. cf.
The first thought was to make it an exact match approach. Andrei thought that the car/cdr one was better, though, and I find it intuitively appealing, too. Perhaps Python missed an important use case?
Or perhaps the ambiguity as to whether the last item gets to be a value or another tuple is too much.
