Expression-literal

Change-expression-literal

Modifying constructor for expression-literal structures.

Syntax

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

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

We construct a new expression-literal 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
