The Scala autocomplete list often loads with a huge list of awful suggestions then moments later adds a bunch of useful options. We are using scala exclusively to write tests for our java code; we are using scalatest for this. The autocomplete for a lot of the (to me, as a non-seasoned scala developer) screwy operator overloaded 'syntax' just doesn't work at all. IDEA does show compile errors etc in 'realtime' (I put that in quotes because it takes a lot longer to catch up with bad scala code than it does bad java code).
