Expression-call

Change-expression-call

Modifying constructor for expression-call structures.

Syntax

(change-expression-call x 
                        [:function <function>] 
                        [:types <types>] 
                        [:arguments <arguments>])

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

We construct a new expression-call 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
