With def, it will be :
user=> (def ^{:private true} foo "ba")
#'user/foo
user=> (meta (var foo))
{:ns #<Namespace user>, :name foo, :file "NO_SOURCE_PATH", :line 4, :private
true}
user=>
It's with defn that you can use a map at a certain position:
user=> (defn foo {:private true} [] "bar")
#'user/foo
user=> (meta (var foo))
{:ns #<Namespace user>, :name foo, :file "NO_SOURCE_PATH", :line 7,
:arglists ([]), :private true}
user=>
