Swcase

Change-swcase

Modifying constructor for swcase structures.

Syntax

(change-swcase x 
               [:value <value>] 
               [:body <body>])

This is an often useful alternative to make-swcase.

We construct a new swcase 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.

                           (:body . swcase->body))

                         'nil))
