Bool

Change-bool

Modifying constructor for bool structures.

Syntax

(change-bool x 
             [:get <get>])

This is an often useful alternative to make-bool.

We construct a new bool 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.

Macro: change-bool

                         'change-bool
                         'nil))
