Eiffel seemed like a really good language. I wish it had succeeded more and become mainstream. I've tried it out some with EiffelStudio earlier. Their support for developing GUI apps, at least on Windows, also seemed good, based on what I tried of it. The book "Object-Oriented Software Construction" by Bertrand Meyer, Eiffel creator, is also very good. I had read most of it some years ago.
