First impressions: I like the look of this language/IDE. It's not general purpose but it seems to be good at what it does. I think live programming - where you make changes to your code and immediately see the effect without having to recompile and restart your system - is the way forward. The adoption of literate programming is interesting - I think commenting code is unsatisfactory for a variety of reasons and am looking for an alternative, and Knuth's idea might be worth building on. The other idea I like is the ability to point at a widget and find out the code that draws it - that makes debugging a lot easier.
