Closure-output

Change-closure-output

Modifying constructor for closure-output structures.

Syntax

(change-closure-output x 
                       [:reg <reg>] 
                       [:type <type>])

This is an often useful alternative to make-closure-output.

We construct a new closure-output 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
