def already adds metadata on the symbol as metadata on the var. Did
you need more than this (below)?
user> (def ^{:doc "foo"} x [1 2 3])
#"user/x
user> (meta (var x))
{:ns #<Namespace user>, :name x, :doc "foo", :line 1, :file "NO_SOURCE_FILE"}
user> (doc x)
-------------------------
user/x
foo
nil
user> (defn ^{:doc "foo foo"} xx [] (println "hello"))
#'user/xx
user> (meta (var xx))
{:arglists ([]), :ns #<Namespace user>, :name xx, :doc "foo foo",
:line 1, :file "NO_SOURCE_FILE"}
user> (doc xx)
-------------------------
user/xx
([])
foo foo
nil
