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. Jules
