What sequence types to have

[lassik]

How about the following sequence types fo Twinjo:

• list (A list of the most convenient type in the host language: either a vector or a proper linked list.)

• vector (Definitely a vector.)

• llist (Definitely a proper linked list.)

• dotted-llist (A linked list with the given tail. If the tail is a proper linked list, the result is also a proper linked list. Otherwise the result is an improper linked list.)

How to represent circular lists?
