Member-designor-sub

Change-member-designor-sub

Modifying constructor for member-designor-sub structures.

Syntax

(change-member-designor-sub x 
                            [:member <member>] 
                            [:index <index>])

This is an often useful alternative to make-member-designor-sub.

We construct a new member-designor-sub 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.
