Another little quibble:

If I run the following

> module Main where
> import Array

> main = (putStr . show . bounds . array (0,-1)) ([]::[(Integer,Char)])

with ghc I get (0, -1), but with hugs I get 

Program error: index: Index out of range

As far as I can interpret the library report, ghc is correct in this
respect.  Moreover, I think that is what we should get, since an empty
array is useful.  So perhaps I should simply be reporting a bug in
hugs, but I thought I'd check here to be sure that everyone agrees
that this is correct.
