A primitive assignment expression has the following form:

(set! <variable> <expression>) - <expression>

This expression is evaluated, and the resulting value is stored in the location to which <variable> is bound. The location to which <variable> is bound must be either in some region enclosing the set! expression or at top level. The result of the set! expression is unspecified.

(define test 1)

(set! test 2)

;; 1

Example 1-5.
