Simple data types in System.Posix.IO should have Eq, Ord, etc. instances
When trying to use OpenMode
in a Data.Map
key, I noticed that it's not an instance of Ord
or even Eq
. Nor are OpenFileFlags
, FdOption
, LockRequest
. I don't see particularly meaningful orderings for them, but meaningless orderings would be useful nonetheless.
