    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

    (defmacro change-bool (x &rest args)
      (std::change-aggregate 'bool
                             x args '((:get . bool->get))
                             'change-bool
                             'nil))
