(boundrw-substlist-p x) → std::bool
This is an ordinary std::deflist. It is
"loose" in that it does not care whether
Function:
(defun boundrw-substlist-p (x) (declare (xargs :guard t)) (let ((__function__ 'boundrw-substlist-p)) (declare (ignorable __function__)) (if (consp x) (and (boundrw-subst-p (car x)) (boundrw-substlist-p (cdr x))) t)))
