With

    (setq foo-hook '(grok greed gold))

I can by inspection learn what the hook is. I don't
need the help or evaluation of the variable name or
anything. I need just bring up the definition itself
and read.

With

    (add-hook 'foo 'grok)
    (add-hook 'foo 'greed)
    (add-hook 'foo 'gold)

I see only what functions are at that point added -
not them already there, or if any. It is also
more bulky.

With `setq' I can add and remove functions by editing
the one form (and evaluating it), without using
`add-hook' or `remove-hook' or anything at all.
