Expr-va-arg

Change-expr-va-arg

Modifying constructor for expr-va-arg structures.

Syntax

(change-expr-va-arg x 
                    [:list <list>] 
                    [:type <type>])

This is an often useful alternative to make-expr-va-arg.

We construct a new expr-va-arg 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.
