Expression-tuple

Make-expression-tuple

Basic constructor macro for expression-tuple structures.

Syntax

(make-expression-tuple [:components <components>])

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

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

Definition

                       'make-expression-tuple
                       nil))

Function: expression-tuple

(defun expression-tuple (components)
  (declare (xargs :guard (expression-listp components)))
  (declare (xargs :guard t))
  (let ((__function__ 'expression-tuple))
    (declare (ignorable __function__))
    (b* ((components (mbe :logic (expression-list-fix components)
                          :exec components)))
      (cons :tuple (list components)))))
