Reference-external

Change-reference-external

Modifying constructor for reference-external structures.

Syntax

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

This is an often useful alternative to make-reference-external.

We construct a new reference-external 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.
