Hi all!
(I'm on 7.0)
Just to jump right to the point here are the hash example lines from the User
Guide and a few added lines with comments that should make it clear what I am
confused about:
(define ht (make-hash))
(hash-set! ht "apple" '(red round))
(hash-set! ht "banana" '(yellow long))
(writeln ht)
(writeln (list? (hash-ref ht "apple")))
;; This is how I assumed hash->list to behave:
(writeln (for/list ([key (hash-keys ht)])
(list key (hash-ref ht key))))
;; This is how it behaves:
(writeln (hash->list ht))
This is the output I get:
#hash(("banana" . (yellow long)) ("apple" . (red round)))
#t
(("apple" (red round)) ("banana" (yellow long)))
(("banana" yellow long) ("apple" red round))
So I'm confused why the list is "flattened" by hash->list. I can manage the
situation using for/list, I'm just wondering.
Thanks,
Jussi
