Name-indexed

Change-name-indexed

Modifying constructor for name-indexed structures.

Syntax

(change-name-indexed x 
                     [:base <base>] 
                     [:index <index>])

This is an often useful alternative to make-name-indexed.

We construct a new name-indexed 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

This is an ordinary change- macro introduced by fty::defprod.

                           (:index . name-indexed->index))
                         'change-name-indexed
                         'nil))
