Ugly yes, but not that expensive. Depending on the list length testing
the additional not-ready variable can even be slower.
If you use CL macros, something can be done about the ugliness, though.
It could be written like this
(defun get-mode-line-struct (type)
(dotimes (i (length mode-line-array))
(when (equal type (mode-line-struct-type (aref mode-line-array i)))
(return (aref mode-line-array i)))))
You're using a vector, probably because you're used to it. Since you're
not doing random-access, a list would be more "natural" in lisp.
(defun get-mode-line-struct (type)
(dolist (s mode-line-array)
(when (equal type (mode-line-struct-type s))
(return s))))
