Constraint-rule

Change-constraint-rule

Modifying constructor for constraint-rule structures.

Syntax

(change-constraint-rule x 
                        [:thmname <thmname>] 
                        [:lit-alist <lit-alist>] 
                        [:syntaxp <syntaxp>])

This is an often useful alternative to make-constraint-rule.

We construct a new constraint-rule 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 defprod.
