Hello, I am trying to use the Lazy Racket for generating infinite lists.
Here's the code:
#lang lazy
(require racket/list)
(define hamming
(list 1
(append-map
(lambda (x) (list
(* 2 x)
(* 3 x)
(* 5 x))) hamming)))
(define bla (take 5 (sort hamming <)))
However, when I evaluate (! bla) I get:
append: expected argument of type <proper list>; given #<promise>
If I understand correctly this happens because I mix racket/list and
lazy? How can I avoid this? Should I use stream-cons?
Thank you.
