Statement-switch

Change-statement-switch

Modifying constructor for statement-switch structures.

Syntax

(change-statement-switch x 
                         [:target <target>] 
                         [:cases <cases>] 
                         [:default <default>])

This is an often useful alternative to make-statement-switch.

We construct a new statement-switch 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.
