Declon-declon

Change-declon-declon

Modifying constructor for declon-declon structures.

Syntax

(change-declon-declon x 
                      [:extension <extension>] 
                      [:specs <specs>] 
                      [:declors <declors>])

This is an often useful alternative to make-declon-declon.

We construct a new declon-declon 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.
