### 13`` Finding Mutated Variables

Sam Tobin-Hochstadt <samth@ccs.neu.edu>

(require unstable/mutated-vars)

This library is unstable; compatibility will not be maintained. See Unstable for more information.

(find-mutated-vars stx) → void?
stx : syntax?

Traverses stx, which should be module-level-form in the sense of the grammar for fully-expanded forms, and records all of the variables that are mutated.

(is-var-mutated? id) → boolean?
id : identifier?

Produces #t if id is mutated by an expression previously passed to find-mutated-vars, otherwise produces #f.

Examples:
> (find-mutated-vars #'(begin (set! var 'foo) 'bar))
> (is-var-mutated? #'var)
#t
> (is-var-mutated? #'other-var)
#f
