It was just this:

--8<---------------cut here---------------start------------->8---
(let* ((hi-lock-face-defaults
        (list
         "hi-yellow"
         "hi-pink"
         "hi-green"
         "hi-blue"
         "hi-black-b"
         "hi-blue-b"
         "hi-red-b"
         "hi-green-b"
         "hi-black-hb")))
  (completing-read
   (format "Highlight using face (default %s): "
           (car hi-lock-face-defaults))
   (all-completions "" obarray)
   'facep t nil 'face-name-history hi-lock-face-defaults))
--8<---------------cut here---------------end--------------->8---

with helm-mode on.

AFAICT we don't try to manipulate obarray directly (of course).  What
nasty things could we be doing?


Thanks,
