Reference-value-pointer

Change-reference-value-pointer

Modifying constructor for reference-value-pointer structures.

Syntax

(change-reference-value-pointer x 
                                [:get <get>])

This is an often useful alternative to make-reference-value-pointer.

We construct a new reference-value-pointer 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
