It's exposed but not documented.  When we wrote it, the .Base module was a 
convenient way to structure the implementation, we didn't intend it to be 
imported outside of the base package.  By the time we started using Cabal and 
had the choice whether to expose modules or not, code was already using 
Data.Array.Base (possibly my own code, I don't remember :-), so we left it exposed.

We should really hide Data.Array.Base, and move out of it the things that we 
really want to expose.  Perhaps Data.Array.Unsafe?
