Tyname-info

Change-tyname-info

Modifying constructor for tyname-info structures.

Syntax

(change-tyname-info x 
                    [:type <type>])

This is an often useful alternative to make-tyname-info.

We construct a new tyname-info 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

                         'change-tyname-info
                         'nil))
