AFAICT this is not quite right. It is supported in Elixir, but not in 
Erlang. There is a proposal to add it to Erlang, but the corresponding 
PR is still open, which indicates that it is not accepted yet: 
https://www.erlang.org/eeps/eep-0055

It's not surprising to me that Elixir supports it, since Elixir is 
heavily inspired / influenced by Ruby.
