Here's my assessed difficulty level in a list that's relatively easy to parse/automate, in the format $filename - $difficulty.

I added 4 difficulty levels: easy, intermediate, advanced, and "burn" (which are the monstrous/black-magical articles, mostly about esoteric Scala features). If "burn" isn't descriptive enough, I'm open to a better term, or to simply caling those articles "advanced" as well.
