Path

Change-path

Modifying constructor for path structures.

Syntax

(change-path x 
             [:get <get>])

This is an often useful alternative to make-path.

We construct a new path 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

                         'nil))
