Collection equality koan is confusing

[rosschapman]

I was a bit confused by the koan here because switching the value order of the list elements causes the test to fail. I'd like to propose either changing the koan to reflect the Clojure guides more closely by saying "Equality with sequential collections is in terms of value and order" or add distinct challenges for both ordered and unordered lists. What do you think?

[nihilismus]

I would put it as "Equality between a list and a vector depends on the value and position of their elements".

Maps and Hashes can also be treated sequentially (map, filter & reduce), but their semantic when it comes to equality does not depend on position.

user=> (map identity (hash-map 10 20 30 40 50 60))
([50 60] [30 40] [10 20])
user=> (map identity (hash-set 10 20 30 40 50 60))
(20 60 50 40 30 10)
user=> (= (hash-map 10 20 30 40 50 60) (hash-map 30 40 10 20 50 60))
true
user=> (= (hash-set 10 20 30 40 50 60) (hash-set 30 50 10 20 40 60))
true
user=> (= (list 10) (hash-set 10))
false
user=> (= (vector 10) (hash-set 10))
false
user=> (= (list 10 20) (hash-map 10 20))
false
user=> (= (vector 10 20) (hash-map 10 20))
false
user=> (= (vector 10 20) (hash-map 0 10 1 20))
false
