The section on extension paths includes an example of using extension paths with indices, but does not really emphasize this capability. As a result, many authors aren't aware that you can do this.
In fact, the section on extension paths often refers to the paths as if they point to a single extension rather than a sub-array of the extension array -- so we may want to clean up that language to be more precise.
