Many of the popular web frameworks like Django and Elixir have a lot in common with Rails with regards to typing and compilation or lack thereof.

Function composition and partial function application is totally supported in Ruby so not sure what your complaint is there. Here is one rather forced example: http://genua.github.io/ruby/2015/03/17/ruby-function-composi...

I don’t know anything about Elm and Purescript but I’ll look into them. They aren’t hugely popular (as far as I know, feel free to correct me) so I’m not sure that’s a major win for portable skills versus Ruby engineers learning Scala or Python. If you don’t get too wild with the symbols, Scala can actually look quite familiar to Ruby programmers. Twitter had people use a subset of Scala when they transitioned many services from Ruby to Scala so that it would be an extra easy transition.

JavaScript has come a long way though and is certainly the lingua franca of the Internet.

    pp_proc = self.method("pretty_print_me").to_proc

Exactly :(

I did say it was a forced example ;)

Even assuming you implemented it their way, their code isn't very concise. In the snippet you pasted, "self.method" could be replaced with "method" for example without changing anything
