Scheme help

[chrisbrown]

I've run into an interesting dilema:

I have a function that consumes a natural number n and produces a list of length n, where each item is a result of a (read) call:

Scheme:

(define (make-list n)   (cond [(zero? n) empty]         [else (cons (read) (make-list (sub1 n)))]))

I also have this function which consumes a function, determines its arity (the number of parameters it consumes), and returns a (make-list) of that length

Scheme:

(define (param-list f)   (define n (procedure-arity f))   (make-list n))

My question is this: is there some way for test-fcn to return the result of f with the values in plist as its arguments? (Assuming f takes a constant number of arguments)

Scheme:

(define (test-fcn f)   (define plist (param-list f))) ;;  ???) ;; ??? should be the result of (f (first plist) (second plist) ... (last plist)) where plist is of arbitrary length ;; Edit: ??? = (apply f plist)

Nevermind, found the solution.
