1270	STUArray and IOUArray lack an Eq instance	jcpetruzza@…	igloo	"Data.Array.IO.IOArray and Data.Array.ST.STArray have Eq instances defined, but their unboxed counterparts (IOUArray and STUArray) have not.

On certain scenarios, this makes switching from boxed to unboxed arrays much harder than necessary.

Furthermore, comments on the sources suggest that the Eq instance for unboxed mutable arrays were accidentally ommited; e.g., from Data/Array/IO.hs:

{{{
module Data.Array.IO (
  ...
   -- * @IO@ arrays with unboxed elements
   IOUArray,		-- instance of: Eq, Typeable
}}}"	merge	closed	normal	6.8.1	libraries/base	6.6	fixed			Unknown/Multiple	Unknown/Multiple		Unknown
