Expr-memberp

Make-expr-memberp

Basic constructor macro for expr-memberp structures.

Syntax

(make-expr-memberp [:arg <arg>] 
                   [:name <name>])

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

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

Definition

                       'make-expr-memberp
                       nil))

Function: expr-memberp

(defun expr-memberp (arg name)
  (declare (xargs :guard (and (exprp arg) (identp name))))
  (declare (xargs :guard t))
  (let ((__function__ 'expr-memberp))
    (declare (ignorable __function__))
    (b* ((arg (mbe :logic (expr-fix arg) :exec arg))
         (name (mbe :logic (ident-fix name)
                    :exec name)))
      (cons :memberp (list arg name)))))
