I agree with the idea behind this proposal, but am pretty sure it will
break quite a few filepath things that I maintain. So +1, but also +1
for a really strong release announcement and version bump.
The problem with filepaths is that they lack much structure, and are
very system dependent - meaning every change will break something. A
lovely abstract type would be wonderful, but no one has yet released
such a library on hackage...
Thanks, Neil

Neil's comprehensive test suite still passes with the new patch.
Ticket, with new patch attached:
http://hackage.haskell.org/trac/ghc/ticket/2034
The discussion deadline has long passed, so I propose we have another 2 weeks (18 November).
I support this new proposal.
To summarise for people who have not been paying full attention:
Currently: takeDirectory "Main.hs" = ""
Proposed: takeDirectory "Main.hs" = "./"
The purpose being that one can always take the directory and get a valid path to use with a file system function, eg createDirectory.
Unchanged behaviour:
"./" "Main.hs" = "./Main.hs"
It was initially proposed that eat "./" on the left hand side but the current proposal leaves the behaviour of unchanged.
