Given your breadth of experience, I actually bet you could get very comfortable with Elixir in a week's time. Especially so if you've worked with Scheme, Ruby, and Haskell. Elixir's syntax is very simple, and 90% of your code is data transformation steps strung together with pipes, which really isn't any different from other (functional) languages.
