Programdef-closure

Change-programdef-closure

Modifying constructor for programdef-closure structures.

Syntax

(change-programdef-closure x 
                           [:get <get>])

This is an often useful alternative to make-programdef-closure.

We construct a new programdef-closure 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.

                         'change-programdef-closure
                         'nil))
