BTW, could indent of define-peg-rule be changed from 1 to 2: ------------------------------------------------------------ (defmacro define-peg-rule (name args &rest pexs)   "Define PEG rule NAME as equivalent to PEXS. The PEG expressions in PEXS are implicitly combined with the sequencing `and' operator of PEG grammars."   (declare (indent 1))                   ^^^ to 2 ------------------------------------------------------------ Currently the indentation of define-peg-rule looks strange: ------------------------------------------------------------ (define-peg-rule t--comment () 		 hello 		 world 		 ...) ------------------------------------------------------------ By using (setf (get 'define-peg-rule 'lisp-indent-function) 2), It looks better: ------------------------------------------------------------ (define-peg-rule t--comment ()   hello   world   ...) ------------------------------------------------------------
