Well, by "imperative-functional hybrid" I wasn't going for maximul functional-ness, e.g something like Ocaml or F#.

I was referering to stuff in the current trend of imperative languages with added functional capabilities (from first class functions to closures to macros) and used with a dash (or several) of functional idioms.

So stuff like C#, Scala, etc would qualify. Javascript and Ruby too. And Rust, if it hits off.

And I also had in mind how those and their libs would evolve more "functionaly" going forward to 2020.
