I can't easily picture how you'd hammer it into the language without needing parser changes but an Haskell/ML/Erlang destructuring where things are pulled apart based on types and/or guard conditions and the like could be very interesting.

You might also look at clojure for more inspiration that's a bit closer to the ES6 stuff (I believe).

E.g. where you can have something like [{:keys [foo bar]} arg_map] which pulls the values at the named keys out of arg_map into vars named after the respective keys.
