    These include the structure of finite lists, which can be generated by two operations: Empty constructs an empty list, Cons(x, L) constructs a list by prepending or concatenating value x in front of list L. A list such as [1, 2, 3] is therefore the declaration Cons(1, Cons(2, Cons(3, Empty))). It is possible to describe the location in such a ...

Modern Lisp dialects typically distinguish symbols from strings; interning a given string returns an existing symbol or creates a new one, whose name is that string ...
