All I am getting is this:

array ((1,5),(1,5)) [((1,5),1.0)]

Maybe the behaviour of ghc was changed since the article was written.

I think you've made a common mistake here. Array bounds are (lower in all dimensions, upper in all dimensions). So perhaps you intended to use the bounds ((1,1), (5,5)) in your code?

I make this mistake frequently.
