Hi Proposal: Add System.FilePath.Cygwin Ticket at: http://hackage.haskell.org/trac/ghc/ticket/3274 I propose we add the module System.FilePath.Cygwin to the filepath library. This module would be based on System.FilePath.Windows but with '/' as the preferred path separator, rather than '\\' as for Windows. This module would never be available as System.FilePath, and would always have to be imported specifically if wanted. The desire for this module comes from working with the Cygwin shell, which supports Windows syntax but requires the alternative separator. I have been using such a module for a few months, and find it very useful. There are no backward compatibility concerns, as it is a new separate module. Discussion deadline: 18th June 2009. Thanks, Neil
