The "Scala Worksheet" feature of the Scala IDE plugin sounds pretty nice. Apparently it's a multi-line REPL, where changes automatically get compiled & evaluated upon save.

I'm having some trouble figuring out how to get it installed in my Eclipse, though. I already had an older version of Scala IDE installed, and apparently this is a fairly new feature. I tried the latest milestone, which is supposed to have it, but I don't see New --> Scala Worksheet when I try to create one.

Has anybody fought this dragon and won?

Edit: I have found my own answer. The trick was to use the following URL as the "update site" when installing ScalaIDE. When you do, the "Scala Worksheet" plugin will appear under the list of available software.
