This is a step in the right direction. I'm always looking for new tools that help in understanding code bases and streamline workflows.

The inline table is cool. I like the idea of embedded documentation like that, as long as its structured in a way that can be turned on-off.

The Scala plugins for Intellij and Eclipse both have worksheets, which I think as of REPLs on steroids.

The one thing I'm still missing from most mainstream development environments though is interaction of live, running programs - the kind seen in Common Lisp and Smalltalk.

Java has it kindof, then enhanced more with JavaRebel (a commercial tool). .NET edit-n-continue is still frustratingly crippled in many ways.

I still feel like I'm programming in a batch environment instead of "molding" my code though.
