Problem with multimethods

[chrisbetz]

Please check out this code in LightTable:

(defn dispatch-updates [entity-type & _] entity-type)

(defmulti updates dispatch-updates)

(defmethod updates :default [entity-type context known-versions & uids]
:anything-else
)

(defmethod updates :Edition [entity-type context known-versions & uids]
:asking-for-a-single-edition
)

(updates :Edition nil nil)

Results in

defn dispatch-updates [entity-type & _] entity-type)

(defmulti updates dispatch-updates)|| => nil||

(defmethod updates :default [entity-type context known-versions & uids]
:anything-else
)|| => clojure.lang.MultiFn@4f3e9f6f||

(defmethod updates :Edition [entity-type context known-versions & uids]
:asking-for-a-single-edition
)|| => clojure.lang.MultiFn@4f3e9f6f||

(updates :Edition nil nil)|| => :anything-else||

However, the call to (updates :Edition nil nil) should result in (and it does in any other Clojure 1.3 REPL) :asking-for-a-single-edition.

Multi-method don't seem to work at the moment

(defmulti foo identity)
(defmethod foo 1 [_] :long)
(defmethod foo 2 [_] :longer)
(defmethod foo :default [_] :endless)
(foo 1) => :long
(foo 2) => :long
(foo 2) => :long

Whereas in the regular REPL the output is:

(defmulti foo identity)
(defmethod foo 1 [_] :long)
(defmethod foo 2 [_] :longer)
(defmethod foo :default [_] :endless)

(foo 1) => :long
(foo 2) => :longer
(foo 3) => :endless
