@hackage explicit-iomodes0.6.0.5

The module System.IO.ExplicitIOModes exports a Handle to a file which is parameterized with the IOMode the handle is in. All operations on handles explicitly specify the needed IOMode. This way it is impossible to read from a write-only handle or write to a read-only handle for example.

See the explicit-iomodes-bytestring and explicit-iomodes-text packages for ByteString / Text operations.
