 9.2 Kinds of Forms
 ==================
 
 A Lisp object that is intended to be evaluated is called a “form” (or an
 “expression”).  How Emacs evaluates a form depends on its data type.
 Emacs has three different kinds of form that are evaluated differently:
 symbols, lists, and all other types.  This section describes all three
 kinds, one by one, starting with the other types, which are
 self-evaluating forms.

· Self-Evaluating Forms   Forms that evaluate to themselves.
· Symbol Forms            Symbols evaluate as variables.
· Classifying Lists       How to distinguish various sorts of list forms.
· Function Indirection    When a symbol appears as the car of a list,
                               we find the real function via the symbol.
· Function Forms          Forms that call functions.
· Macro Forms             Forms that call macros.
· Special Forms           Special forms are idiosyncratic primitives,
                               most of them extremely important.
· Autoloading             Functions set up to load files
                               containing their real definitions.
