Haskell

If Haskell were on there, I'd at least transliterate the Python example from the video as a contribution ;)

Another vote for Haskell.

Language support is super easy to add. Any list of libraries you'd really want with Haskell?

Some random highly used libraries:

containers, bytestring, mtl, text, transformers, time, array, aeson, split, blaze-builder, blaze-html lens, safe, resourcet

I'm sure aeson examples would be very popular. mtl/transformers examples for those who are getting to them in the learning process.

Here is a complete list of the top reverse dependencies for libraries on hackage:

You are brilliant. Thank you so much.

If it's easy, Clojure with support for arbitrary libraries via leiningen would be great :)

Prelude's support libraries plus at least the curl package: https://hackage.haskell.org/package/curl
