Lists

A list is a sequence of zero or more objects, the main difference between lists and vectors is that lists are more dynamic: they can change size, be split, reversed, concatenated, etc... very easily.

In Lisp lists are not a primitive type; instead singly-linked lists are created by chaining cons cells together (see section Cons Cells).

Function: listp object

This functions returns t when its argument, object, is a list (i.e. either a cons cell or nil).
