I was reminded of that tonight when I went looking for a rich text REPL environment. I'm sure such a beast is out there. Something called Leo might even be it, but after looking at the screen shots, beginners guide and FAQ, I still don't really know what it's all about, or feel at all inspired to give it a shot.
Compare and contrast with 'try ruby'
