Expr-memberp

Change-expr-memberp

Modifying constructor for expr-memberp structures.

Syntax

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

This is an often useful alternative to make-expr-memberp.

We construct a new expr-memberp structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

                           (:name . expr-memberp->name))

                         'remake-expr-memberp))
