Hmm, I didn't think of this interpretation.  If this is the right one, then 
maybe it should be made more clear that the sentence in the array 
documentation doesn't mean Prelude.undefined.

In addition, I would like as little undefinedness as possible, i.e., different 
implementations behaving as similar as possible.  So I'd be happy if the 
handling of duplicate indices was defined by the library specification.
