It seems to me that one of the things that's valuable about this feature is that 
one can make as regular visible data any calculated-from-a-row value that is 
used for indexing purposes rather than that being hidden or not possible.  I 
assume or hope that generated columns can be used in all index types like 
regular columns right? -- Darren Duncan
