Namespaced IO Layer
The Haskell I/O library is based on the underlying Unix/Posix concepts, repeating its well-known design specifics and inconsistencies. The namespaced IO library provides an IO abstraction based on the ideas found in Plan 9 and Inferno, that is, to represent each IO capable resource as a virtual file server exposing a tree of files and directories, organizing those trees using per-process configurable namespaces.
