Literal-field

Change-literal-field

Modifying constructor for literal-field structures.

Syntax

(change-literal-field x 
                      [:value <value>])

This is an often useful alternative to make-literal-field.

We construct a new literal-field 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.
