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