Clojurians Log v2

Hi there, does empty 's implementation currently work on records? I get:

(def POST-ORDER-TREE-VALS
  (specter/recursive-path [] p
    (specter/cond-path
     map? (specter/continue-then-stay [specter/MAP-VALS p])
     sequential? [specter/ALL p]
     set? [specter/ALL p]
     specter/STAY)))

maybe that map? needs to become record? or something? Trying in the REPL
