The Lisp Reader
---------------

   Lisp programs and functions are stored internally as Lisp data
objects, the Lisp Reader is the mechanism that translates from textual
descriptions of Lisp objects to the internal data structures
representing them.

   The Lisp Reader is the collection of internal functions accessed by
the `read' Lisp function. It reads a character at a time from an input
stream until a whole Lisp object has been parsed.

   Note: Data Types.
