Data.HashTable (and thus Data.Array.*) is used in the implementation of Data.Typeable. It also differs from the others in being a mutable data structure. I imagine that without it this package wouldn't need to depend on array and concurrent. Data.Monoid could possibly go here too. Another possibility is to split the 4 class modules from the concrete data structures.
