Symbols
*******

   A "symbol" is an object with a unique name.  This chapter describes
symbols, their components, their property lists, and how they are
created and interned.  Separate chapters describe the use of symbols as
variables and as function names; see Note: Variables, and Note:
Functions.  For the precise read syntax for symbols, see Note: Symbol
Type.

   You can test whether an arbitrary Lisp object is a symbol with
`symbolp':

 - Function: symbolp object
     This function returns `t' if OBJECT is a symbol, `nil' otherwise.

Symbol Components

Symbols have names, values, function definitions

and property lists.

Definitions

A definition says how a symbol will be used.

Creating Symbols

How symbols are kept unique.

Property Lists

Each symbol has a property list

for recording miscellaneous information.
