Tree-leafterm

Change-tree-leafterm

Modifying constructor for tree-leafterm structures.

Syntax

(change-tree-leafterm x 
                      [:get <get>])

This is an often useful alternative to make-tree-leafterm.

We construct a new tree-leafterm 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.
