C has "classical" tooling like Cscope and Exuberant Ctags. The stuff works very well, except on the odd weird code that does idiotic things that should not be done with preprocessing. Even for Lisp, you don't want to be grepping, or at least not all the time for basic things. For TXR Lisp, I provide a program that will scan code and build (or add to) your tags file (either a Vim or Emacs compatible one). Given (defstruct point () x y) it will let your editor jump to the definition of point, x and y.
