This leads me to the following conclusion: Any number of pared nested
parentheses is equivalent in this case, i.e., all the following forms
are valid and equivalent:

:hook ((prog-mode text-mode latex-mode) . ace-jump-mode))
:hook (((prog-mode text-mode latex-mode) . ace-jump-mode)))
:hook ((((prog-mode text-mode latex-mode) . ace-jump-mode))))

But according to my tries, all the above three forms work, but the
following ones don't:

:hook (((((prog-mode text-mode latex-mode) . ace-jump-mode)))))
:hook ((((((prog-mode text-mode latex-mode) . ace-jump-mode))))))

Any hints for this phenomenon?
