Macro-info-object

Change-macro-info-object

Modifying constructor for macro-info-object structures.

Syntax

(change-macro-info-object x 
                          [:replace <replace>])

This is an often useful alternative to make-macro-info-object.

We construct a new macro-info-object 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.
