This seems like a good thing, but it made me curious as to how many
(function (lambda ...)) things there are in Emacs.  Just naive grepping
showed me ~300 of them; I'm guessing there's even more.

Most look like they can definitely be removed:

          (setq split-by-major-mode
                (sort split-by-major-mode
                      (function (lambda (elt1 elt2)
                                  (> (length elt1) (length elt2))))))

But there's a lot of these things:

(put 'pascal 'math-radix-formatter
     (function (lambda (r s)
                 (if (= r 16) (format "$%s" s)
                   (format "%d#%s" r s)))))

Does the `function' here have any meaning, or is it superfluous?
