Hi guys, Which is preferable? (define (foo let … (acc empty)) … (foo (rest let) ... (cons …. acc))
or (define (foo lst ...) (let loop ([lst lst] …[acc empty]) … (loop (rest let) … (cons …. acc))) On the one hand we eliminate the named let construct, but on the other hand we expose the acc in the function / contract. If the acc is not something the caller would ever need to know about, should we hide it inside the definition? -Kevin ____________________ Racket Users list: http://lists.racket-lang.org/users
