Expression-add

Make-expression-add

Basic constructor macro for expression-add structures.

Syntax

(make-expression-add [:arg1 <arg1>] 
                     [:arg2 <arg2>])

This is the usual way to construct expression-add structures. It simply conses together a structure with the specified fields.

This macro generates a new expression-add structure from scratch. See also change-expression-add, which can "change" an existing structure, instead.

Definition

                       args '((:arg1) (:arg2))
                       'make-expression-add
                       nil))

Function: expression-add

(defun expression-add (arg1 arg2)
  (declare (xargs :guard (and (expressionp arg1)
                              (expressionp arg2))))
  (declare (xargs :guard t))
  (let ((__function__ 'expression-add))
    (declare (ignorable __function__))
    (b* ((arg1 (mbe :logic (expression-fix arg1)
                    :exec arg1))
         (arg2 (mbe :logic (expression-fix arg2)
                    :exec arg2)))
      (cons :add (list arg1 arg2)))))
