Yup; that'd work.  The stuff that info-look requires, though, is
pretty...  er...  convoluted.  Example:

(info-lookup-maybe-add-help
 :mode 'perl-mode
 :regexp "[$@%][^a-zA-Z]\\|\\$\\^[A-Z]\\|[$@%]?[a-zA-Z][_a-zA-Z0-9]*"
 :doc-spec '(("(perl5)Function Index"
	      (lambda (item)
		(if (string-match "^\\([a-zA-Z0-9]+\\)" item)
		    (match-string 1 item)))
	      "^" "\\b")
	     ("(perl5)Variable Index"
	      (lambda (item)
		;; Work around bad formatted array variables.
		(let ((sym (cond ((or (string-match "^\\$\\(.\\|@@\\)$" item)
				      (string-match "^\\$\\^[A-Z]$" item))
				  item)
				 ((string-match
				   "^\\([$%@]\\|@@\\)?[_a-zA-Z0-9]+" item)
				  (match-string 0 item))
				 (t ""))))
		  (if (string-match "@@" sym)
		      (setq sym (concat (substring sym 0 (match-beginning 0))
					(substring sym (1- (match-end 0))))))
		  (if (string-equal sym "") nil sym)))
	      "^" "\\b"))
 :parse-rule "[$@%]?\\([_a-zA-Z0-9]+\\|[^a-zA-Z]\\)")

I'm not sure the maintainer for foo-mode can be expected to understand
any of this stuff (so it's an info-look.el internal thing), but on the
other hand, these days that doesn't make much difference.
