Not looking to knock DrScheme. But my experience was my experience. And hopefully I am not doing any harm by reporting my experience to Mathias. I have never experienced DrScheme in the context of a formal curriculum. And since that is how it is intended to be used, Mathias should not be shocked that perhaps it does not work quite as well outside of that kind of setting. No offense taken. I doesn't kill me if you guys don't understand the power of DrScheme. Just take a look at make executable, formerly called make launcher. Edit your programs with Emacs. Vi, for heaven's sake. Or ignore DrScheme and its lessons. Fine, too. -- Matthias
