Not quite: A close ] matches all open (, but can be stopped short by
an open [.  Open [ were rarely if ever used, but close ] were very
useful, e.g. at the end of a define:

(define foo
 (lambda (x)
   (cond ((eq x 3)(f x))
         (t (y x]

where that ] saves, wait for it, _four_ keystrokes -- one ] instead of
five )!

Outside Interlisp, true AFAIK.  Inside Interlisp, it saw a fair amount
of use, IIRC.
