Hello again, à propos datafiables. There’s a behaviour in printing 'unrepl/browsable literals in combination with nav that I cannot understand. Take a dumb example
(defrecord DN [a b]
clojure.core.protocols/Datafiable
(datafy [this] (into {} this))
clojure.core.protocols/Navigable
(nav [this k v] (clojure.datafy/datafy v)))
(DN. 1 2) and following the first elision for the browsable result in this malformed EDN which makes trouble with the reader:
[:eval (({:a # [nil #unrepl/... {:get (unrepl.repl$4NSDREePlCk74VjoImLYAZy60JQ/fetch :G__785)}], :b # [nil #unrepl/... {:get (unrepl.repl$4NSDREePlCk74VjoImLYAZy60JQ/fetch :G__786)}]})) 6]
nav the wrong way?Andrea 2019-05-24T09:11:34.005700Z
the example above doesn’t comply with rebinding of the variable x at

in the machine printable protocol for browsable tagged literals

It seems that (:tag x) and (:form x) are nil in the above example
