In general, it seems like the authors of Elixir were able to capture more of the cool things about Clojure than LFE. Check out some of the top level functions in Elixir:

  update_in
  put_in
  get_in

http://elixir-lang.org/docs/stable/elixir/Kernel.html#update...

These are basically right out of Clojure. It may seem like a small thing, but consistent, well thought out functions like this makes working with immutable data structures much easier.

"update", "put" are already available in Erlang[0] and work with nested records[1] if I understand correctly. Likewise, it seems that LFE has map-update for the same use cases[2].

Protocols are another major concept that Elixir lifted straight from Clojure. IMO one of the nicest ways of doing ad hoc polymorphism.
