Re: Different behaviour when using (def ^:macro ...) outside top-level
Yeah, it's the difference in behaviour that I don't understand. Thanks for the workaround though Gunnar.

Different behaviour when using (def ^:macro ...) outside top-level
Hi! If I evaluate (def ^:macro my-defn1 #'defn) a macro named 'my-defn1' is defined, which I can use like 'defn'. However, if I use instead (if true (def ^:macro my-defn2 #'defn)) the var for 'my-defn2' doesn't have the :macro metadata set and I can't use it as a macro, even though the 'def' form is equal to the previous case. Here is a paste: http://cljbin.com/paste/52322ba5e4b0fa645e7f9243 What makes the behaviour different?

Re: Different behaviour when using (def ^:macro ...) outside top-level
`def` does not handle `:macro true` metadata on the provided symbol. But you can work around that like clojure.core does, e.g. for the macro `defmacro` after the `(def ... defmacro ...)` call the following is called: `(. (var defmacro) (setMacro))` -- -- You received this message because you are subscribed to the Google Groups Clojure group.
