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