A crock? Now that I've got that macrology out of the way, does not

(my-add-hooks (emacs-lisp lisp lisp-interaction)
  (fun foo))

look better than

(add-hook 'emacs-lisp-mode-hook
   (lambda () (fun foo)))

(add-hook 'lisp-mode-hook
   (lambda () (fun foo)))

(add-hook ....

I think it does :)

Why does this not work:

      (my-add-hook hook ,@body)))


Because you need to write
`(dolist (hook ',hooks)

and then call this with an _unquoted_ list, like
(my-add-hooks (lisp emacs-lisp)

Apart from that, I consider this sort of thing a crock.  What are you
hoping to achieve that you would not be better off doing by a proper
function instead of a macro?
