Macro-table

Change-macro-table

Modifying constructor for macro-table structures.

Syntax

(change-macro-table x 
                    [:alist <alist>])

This is an often useful alternative to make-macro-table.

We construct a new macro-table 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.
