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