Int+denv

Change-int+denv

Modifying constructor for int+denv structures.

Syntax

(change-int+denv x 
                 [:int <int>] 
                 [:denv <denv>])

This is an often useful alternative to make-int+denv.

We construct a new int+denv 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.

                           (:denv . int+denv->denv))
                         'change-int+denv
                         'nil))
