[erlang-questions] question: "Erlang literals are no longer copied when sending messages."

[Benoit Chesneau]

With Erlang 20, "Erlang literals are no longer copied when sending messages" according to the changelog. 
Does it means something like #{ somelist => [], map => #{ } } will be returned from a gen_server call without beeing copied?  (ie the content of somelist and somemap will only be referenced ?
