Escape-x

Change-escape-x

Modifying constructor for escape-x structures.

Syntax

(change-escape-x x 
                 [:get <get>])

This is an often useful alternative to make-escape-x.

We construct a new escape-x 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-escape-x
                         'nil))
