Expression-funcall

Change-expression-funcall

Modifying constructor for expression-funcall structures.

Syntax

(change-expression-funcall x 
                           [:get <get>])

This is an often useful alternative to make-expression-funcall.

We construct a new expression-funcall 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.
