Spec/qual-attrib

Change-spec/qual-attrib

Modifying constructor for spec/qual-attrib structures.

Syntax

(change-spec/qual-attrib x 
                         [:spec <spec>])

This is an often useful alternative to make-spec/qual-attrib.

We construct a new spec/qual-attrib 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
