Is there such a thing as memory-mapped arrays in GHC?
In principle, there could be an IArray instance to memory-mapped files.
(There could also be a mutable version, but just the IArray version
would be useful).
I noticed just the other day that there are some 'obvious' IArray
constructors missing. It ought, for example, be possible to build a new
IArray from an old from a subset of the elements; a dimensional slice
going from an (Int,Int,Int) indexed array to (Int,Int), or a stride
taking 'one element in three' along each axis, etc.
Annoyingly, it doesn't seem to be straightforward to make your own
instances of IArray, since the important methods aren't exported.
I think there is real scope for some expansion here.
