Is there a SLIME equivalent for this editor? When I'm programming C++, there's not really any editor on Linux that's much better than a code formatter. But when I'm working in more civilized languages, I find I want more than just a text editor. That's the thing I love about emacs. For all its wonky glyph rendering and inability to deal with fonts in a rational manner, it's still one of the most truly extensible and modable editors available anywhere.
