OK (I misunderstood you originally but it's not worth explaining :)

Let's go with

   (defun my-move-defun ()
     "docstring"
     :keywords '(move)
     ...)

to be consistent with "Keywords" in the package headers and other
places.

(defun) would need some small changes at the C level to handle this, but
my question was whether I should use the symbol's plist to store the
keywords, or a global hashtable for speed or something else.  It
seems like the symbol plist is the best place logically; are there any
issues with walking the whole namespace to find tags?  I don't want this
to be slow.
