Why does neo4j-clj.core/connect return a map instead of just the Driver object?

[cloojure]

This map is returned:

     {:url        uri,
      :user       user,
      :password   password,
      :db         db
      :destroy-fn #(.close db)}

but only the db is returned. Also, the "db" is actually a Driver object. Why not just return this, with the proper name?

It could then be used directly via with-open in clj code.
