 This will only work for files in that one directory. `__DIR__` won't be
 magic, and so it is really not any use for us. We can already use
 `ABSPATH` or other constants. In fact, that's what we already do. The only
 place that we really use `dirname( __FILE__ )` in core is in files that
 are entry-points of the application. We use that to include the bootstrap,
 and then use `ABSPATH` and other constants after that.

 For plugins, the solution is for them to define their own constants if the
 don't want to use `dirname( __FILE__ )` in every place.
