Macro-info-function

Change-macro-info-function

Modifying constructor for macro-info-function structures.

Syntax

(change-macro-info-function x 
                            [:params <params>] 
                            [:ellipsis <ellipsis>] 
                            [:replace <replace>])

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

We construct a new macro-info-function 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.
