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". The value is computed in a
fashion that depends on the data type of the object, following 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'.
