Uninitialized UArray - feature or bug?

[Tomasz Zielonka]

Hello!

This is a little weird:

Prelude> :m + Data.Array.Unboxed
Prelude Data.Array.Unboxed> let f () = array (1, 5) [] :: UArray Int Int
Prelude Data.Array.Unboxed> f () == f ()
False

Are we giving away purity for efficiency? ;)
If this behaviour is intended, maybe it should be documented?

Maybe it would be a good idea to define default values for types which
can be unboxed?

Regards,
Tom
