Hello James Yes. The (into (empty table) (comp (filter process?) (map process)) table) was exactly what I wanted for an end user to avoid to have to write, but just a (filter ... table), otherwise I could provide a wrapper like (defn myfilter [pred table] (into (empty table) (comp (filter process?) (map process)) table)), which I also wanted to avoid, but you and Alex are both right.
Thank you for taking time.
