Awesome. Is Elixir prevalent in production yet? Will it be?
I think I want to learn either OCaml or Elixir next.
It's probably more prevalent than OCaml at this point despite it's young age. It builds on top of Erlang/OTP which is quite battle tested and used by several major companies. The community behind it is quite strong as well.
Pipes are pretty prevalent in PowerShell too.
Though not as useful as in Bourne shell, as you can't save intermediate
results to review or reprocess them.
