9.2 Kinds of Forms

A Lisp object that is intended to be evaluated is called a form. 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 “all other types” which are self-evaluating forms.

9.2.1 Self-Evaluating Forms   Forms that evaluate to themselves.
9.2.2 Symbol Forms   Symbols evaluate as variables.
9.2.3 Classification of List Forms   How to distinguish various sorts of list forms.
9.2.4 Symbol Function Indirection   When a symbol appears as the car of a list, we find the real function via the symbol.
9.2.5 Evaluation of Function Forms   Forms that call functions.
9.2.6 Lisp Macro Evaluation   Forms that call macros.
9.2.7 Special Forms   "Special forms" are idiosyncratic primitives, most of them extremely important.
9.2.8 Autoloading   Functions set up to load files containing their real definitions.
