My preferred version of Elixir would have been:
1. Take Erlang
2. Make standard library consistent for input params and return values and add some convenience goodies
3. improve tooling (ie. tests, mix, hex etc)
4. add pipeline operator
5. get rid of trailing semicolons and dots
All the other syntactic fluff I really don't need - especially adding 23 new ways of writing the same thing but shorter and less readable, obscured by macros and RoR like convenience overload
