Fconst-dec

Change-fconst-dec

Modifying constructor for fconst-dec structures.

Syntax

(change-fconst-dec x 
                   [:core <core>] 
                   [:suffix? <suffix?>])

This is an often useful alternative to make-fconst-dec.

We construct a new fconst-dec 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.

Macro: change-fconst-dec

                         '((:core . fconst-dec->core)
                           (:suffix? . fconst-dec->suffix?))
                         'change-fconst-dec
                         'nil))
