Description: 

Because the word 'list' appears on PHP's list of reserved keywords, none of the list.module tests could be converted to PSR-4.
To work around this, the functionality of the List module was moved into the Options module.

The Options module provides widgets like checkboxes, radio buttons, and select lists. As the list.info file said "Use with Options to create selection lists." Since the List module required the Options module, and they implement none of the same hooks, all of List's functionality was moved into the Options module.
