For all practical purposes, I find this be sufficient.

(global-set-key (kbd "C-c f")
                (lambda ()
                  (interactive)
                  (require 'finder)
                  (let ((thing (intern (thing-at-point 'symbol))))
                    (if (functionp thing)
                        (find-function thing)
                      (find-variable thing)))))

Put your cursor on a variable or a function, C-c f and you are staring
right at the definition of the variable or function.  For this to work,
the library defining the function or variable should already be loaded.
