Out of curiosity, why is there no MAP-KEYS?

@zane never had a need for it

you can make an inefficient one like this: (def MAP-KEYS (comp-paths ALL FIRST))

Huh. I might be misunderstanding what's happening here, but ALL seems to behave strangely on records.

Is this user error?

(defrecord Test [])
(transform [specter/ALL] identity (->Test))
;; => UnsupportedOperationException Can't create empty: test-ns.Test 

@zane yes

ALL works on vectors, maps, lists, queues

Okay. Thanks, Nathan.
