Let's say you had an eclipse plugin that let you write in lisp, but it actually converted the code to java underneath. You could click a button to switch between views. Are you saying that would be a bad thing? If a tool allows you to be more productive, I use it. Note: I don't use lambda4jdt at all, I just like the idea of creating problem specific views for code and I don't think that belongs at the language level.
You're right, my comment was directed at your example really; the code before and after use the same representation, text. In that case it seems the original was simply a poor textual representation of the logic. I'm actually a firm believer in being able to visualise code. After all coding really gets done in my head and when it's in there it's in 3D images/videos. I long for the day when I can work in an immersive environment where I can walk around the design suspended in the air. That day seems a long way off at the moment though :)
