Scala

Me too. I'd love to see a bit more synthesis in the Scala community, sometimes I feel like "easy" is set in opposition to the more elaborate Scala ecosystem, but as Haoyi points out, easy isn't the same as simple, and we can do brilliant things with fancy scala but then wrap it up behind an "executable pseudocode" interface so users can access the most common cases, at speed and even at scale, very simply and concisely. (That seems like what Haoyi's libraries often do!)
