I recently ran into this problem again.
The solution I came up with is:
(defn filter-printable [obj]
(cond
(or (symbol? obj) (number? obj) (string? obj) (keyword? obj)) obj
(vector? obj) (apply vector (map filter-printable obj))
(seq? obj) (map filter-printable obj)
(set? obj) (into #{} (map filter-printable obj))
(map? obj) (into {} (for [[k v] obj]
[(filter-printable v) (filter-printable v)]))
true [:un-readable (pr-str obj)]))
## example:
(filter-printable
{:k 20
:f 'abc
:d '(+ 1 2 3 foo)
:other (async/chan 10)})
Anyone have a better / more elegant solution?
