Racket - Match Function -

i'm learning how use "match" function in racket i'm not sure how can work in contexts.

for example, problem have use match replace every occurrence of lambda in program word "lumbda".

    > (lambda->lumbda '(lambda (lambda) lambda))      (lumbda (lambda) lambda)

it should change function "lambda" "lumbda", not variables. have no clue how go this.

try this:

(define (lambda->lumbda exp)   (match exp     [(list 'lambda args body) (list 'lumbda args body)]     [_ (error "unknown expression")]))

for example:

(lambda->lumbda '(lambda (lambda) lambda))  => (lumbda (lambda) lambda)
