Got it, sorry for posting too fast.  Making gnus-summary-buffer the
current buffer works, but `gnus-summary-put-mark-as-expirable-next'
is an interactive function.  The following version works fine:

  (add-hook 'gnus-summary-mode-hook 'keramida-alter-summary-map)
  (add-hook 'gnus-article-prepare-hook 'keramida-alter-summary-map)
  (defun keramida-alter-summary-map ()
    (local-set-key "e"
      (lambda (n)
        (interactive "p")
        (gnus-summary-put-mark-as-expirable-next n)))
    (local-set-key "E" 'gnus-summary-edit-article))

Does this seem a reasonable way of writing the hook?  I've never used an
`interactive' lambda before, so I'm not sure if it's considered bad style.
