I’m coming from clojure. Is there an easy way to destructure parameters? (define (foo (a b & xs)) (+ a b)) (foo '(1 2 3))

One possibility is using define/match

See https://docs.racket-lang.org/guide/lambda.html\|https://docs.racket-lang.org/guide/lambda.html

E.g.,

(define/match (foo xs) [((list a b _ ...)) (+ a b)]) (foo '(1 2 3))

Or use match-lambda

(define foo (match-lambda [(list a b _ ...) (+ a b)]))

Ultimately, you are free to create a macro that expands to match to do whatever you want.
