Var/const-sinfo

Change-var/const-sinfo

Modifying constructor for var/const-sinfo structures.

Syntax

(change-var/const-sinfo x 
                        [:type <type>] 
                        [:constp <constp>])

This is an often useful alternative to make-var/const-sinfo.

We construct a new var/const-sinfo 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
