elisp: Evaluation

 
 9 Evaluation
 ************
 
 The “evaluation” of expressions in Emacs Lisp is performed by the “Lisp
 interpreter”—a program that receives a Lisp object as input and computes
 its “value as an expression”.  How it does this depends on the data type
 of the object, according to rules described in this chapter.  The
 interpreter runs automatically to evaluate portions of your program, but
 can also be called explicitly via the Lisp primitive function ‘eval’.
