Different behaviour when using (def ^:macro ...) outside top-level

2013-09-12 Thread André Gustavo Rigon
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?

Thanks!

Yeah, it's the difference in behaviour that I don't understand.

Thanks for the workaround though Gunnar.
