Expr-call

Change-expr-call

Modifying constructor for expr-call structures.

Syntax

(change-expr-call x 
                  [:fun <fun>] 
                  [:args <args>])

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

We construct a new expr-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
