Is there really a clear distinction between IDEs and (some) editors? Eclipse has some language modules that aren't really that great, so would it count as an IDE for those? And Emacs is most definitely an Elisp IDE, nearly a CL IDE with slime and quite close with a few other languages, given enough customization… And while I haven't looked, I bet you can get enough integration with vim, at least on the level of Visual Studio 5… Meanwhile, Smalltalkers know where to draw the line and tell us that we never used an IDE at all (or an object-oriented language)…
