Actually one more question if you guys would care to comment- i'm assuming you guys use sbt. How do you keep a single scala version across all your projects (if you do)? I'm not a fan of repeating scalaVersion := "x" in all the

build.sbt

files. And of course I'd ideally like a single version for packages too (which I can do in global.sbt to an extent. Is that wrong to do?
