Jstatem-if

Change-jstatem-if

Modifying constructor for jstatem-if structures.

Syntax

(change-jstatem-if x 
                   [:test <test>] 
                   [:then <then>])

This is an often useful alternative to make-jstatem-if.

We construct a new jstatem-if 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
