Ask HN: resources for learning functional languages?

Thank you, HN! Last year I was one of "those people:" the guy that would ask for advice on learning how to code, what language to use, what projects to work on.

Well I actually decided to hang around, and I'm comfortable with a few languages (Python, R, a bit of C) a year later, To avoid plateauing, though, I would like to step into Functional Programming Land.

In my experience, functional languages == Scala, so I'd like your suggestions on resources for Scala. Does the above expression evaluate differently to you? If so, can you suggest other languages (and their best resources)?
