[DGD] finding an index by a value

Write your own. And I'll say the obvious: If you find yourself doing 
this fairly often, you need an index in the other direction as well. If 
there were implemented in the driver, it would be a constant factor 
faster (although not as big a constant as you probably think), but you 
would still be in the domain of O(N).
