As a Pythonista, I'm envious that Rubyists have this excellent thing called Elixir to migrate to. I would jump wholesale to Elixir if I could fulfill all my various use cases with it. But at one point I may start using Phoenix for my web stuff.
Definitely keeping my eye on it, and I think these guys (Elixir in particular) nailed the right implementation.
If I had a language I could wish for, a BEAM VM language with Pythonic syntax would be it.
