This is all a preamble to Dotty, the new experimental compiler ("dotc" in the slides), making its way into Scala proper.
When it was first announced some Scalaz core members freaked out on Twitter (due to proposed simplification of the type system), but that died down, apparently the changes won't completely neuter the type system down to that of other JVM languages.
Presumably tooling and build times will improve, along with fewer ways to do the same thing, when Dotty comes on the scene (guessing a couple of years away).
For now, if one makes use of SBT sub projects along with incremental builds in SBT 0.13 (and turns off automatic builds in Eclipse/IntelliJ), one _can_ have a snappy development experience and decent compile times.
Have to learn the ropes though, as with any powerful language, out of the box there are hard yards to get through...
