Read for Arrays does not work

In hugs I can go:

Array> read (show (array (1,1) [(1,42)])) :: Array Int Int
array (1,1) [(1,42)]

whereas ghc gives me:

Main> read (show (array (1,1) [(1,42)])) :: Array Int Int

<interactive>:1:
    No instance for (Read (Array Int Int))
    arising from use of `read' at <interactive>:1
    In an expression with a type signature:
        read (show (array (1, 1) [(1, 42)])) :: Array
Int Int
    In the definition of `it':
        read (show (array (1, 1) [(1, 42)])) :: Array
Int Int


The Haskell Library Report 98 says Read should be defined
for Array a b, with (Read a, Ix a, Read b)
