An irrelevant lifetime.
(irr-lifetime) → acl2::irr
This can be used as a dummy value of the type.
Function:
(defun irr-lifetime nil (declare (xargs :guard t)) (let ((__function__ 'irr-lifetime)) (declare (ignorable __function__)) (lifetime-auto)))
Theorem:
(defthm lifetimep-of-irr-lifetime (b* ((acl2::irr (irr-lifetime))) (lifetimep acl2::irr)) :rule-classes :rewrite)
