Basic constructor macro for value-false structures.
(make-value-false )
This is the usual way to construct value-false structures. It simply conses together a structure with the specified fields.
This macro generates a new value-false structure from scratch. See also change-value-false, which can "change" an existing structure, instead.
This is an ordinary
Macro:
(defmacro make-value-false (&rest args) (std::make-aggregate 'value-false args 'nil 'make-value-false nil))
Function:
(defun value-false nil (declare (xargs :guard t)) (let ((__function__ 'value-false)) (declare (ignorable __function__)) (cons :false (list))))
