Re: Compilable clojure program, but unreadable?
Hi, Is this inconsistent behaviour: user=> `s/foo s/foo user=> ::s/foo # nil user=> (require '[clojure.string :as s]) nil user=> `s/foo clojure.string/foo user=> ::s/foo :clojure.string/foo I think that ::s/foo should be resolved to :s/foo if there is no alias for s (like symbols).

The reader page says, with :: they are resolved in the current namespace. And this seems to work since they where introduced: user=> (require '[clojure.string :as s]) nil user=> ::s/join :clojure.string/join user=> `s/join clojure.string/join Just as s/join gets resolved to the clojure.string/join, ::s/join gets resolved to :clojure.string/join. Sounds consistent and not in violation of the reader page. Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.

The syntax ::s/kwd is incorrect syntax: it should be either ::kwd (which will resolve in the current namespace) or :s/kwd (only one colon). -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Compilable clojure program, but unreadable?
Hi, Clojure doesn't read files. It reads, compiles and executes a stream of toplevel expressions. Hence the file is compilable, but not readable. If you do not want to execute the forms contained in a file, you have to avoid any dynamic feature. In particular aliased keywords with :: since those can only be handled after the require is executed.

Hi If I have the following short Clojure program: ;; unread.clj (require '[clojure.string :as s]) (prn ::s/kwd) The second form can't be read by the clojure reader: user=> (def reader (java.io.PushbackReader.
