Hello. I was wondering if there might be any relatively simple way to implement a type equivalent to UArray, but with the memory stored in a ForeignPtr? It seems like this would be a commonly useful situation, where you have a C function that returns a pointer to an array of data, and it would be nice to be able to access that data without making a copy of it.
StorableArray does this for mutable arrays, and this is the way the CVS version of Hugs implements UArray (cf hugs98/libraries/Hugs/ByteArray.hs).
