Sebastian Benz blogged about a REPL (Read-Eval-Print loop) he implemented for Xbase.
He also wrote a very good introduction to explain what Xbase is and why it is such an important addition to the Xtext framework.
His blog isn't yet included in Eclipse Planet, so I wanted to makes sure that you won't miss it.
I think the REPL is a great way to explore the power of a language. Maybe we should use it in the proposed EclipseCon tutorial if it's getting accepted. :-)
