It is sad there is no "cons" or "llist" built-in type, something like: mycons = cons(car, cdr) mylist = llist(iterable) Of course we can write [car, cdr] or (car, cdr) for making linked lists in pure Python (without having to define class types), but both have issues.The first is storage inefficient, the latter is not mutable. Yes I know Guido left out linked lists for a purpose, so there is probably no use complaining on the Python ideas of Python dev lists...
