> How come we don't have Google Maps-like zooming with LOD mapping to abstractions at different levels? With macroexpand-* family of emacs+slime, which I use all the time, I do have access to this. I haven't done any Aspect-Oriented Programming, but suppose it wouldn't be impossible to get similar functionality with it too. A lesser form I use often with non-Lisp languages is narrow-to-defun and narrow-to-region, especially when I need to look at more than one area of code simultaneously.
