Value-object

Change-value-object

Modifying constructor for value-object structures.

Syntax

(change-value-object x 
                     [:members <members>])

This is an often useful alternative to make-value-object.

We construct a new value-object 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

This is an ordinary change- macro introduced by fty::defprod.
