New official language extension tokens for GHC 7.8.1
Hello GHC Devs, Which of the language extensions listed in `expectedGhcOnlyExtensions` in http://ghc.haskell.org/trac/ghc/browser/testsuite/tests/driver/T4437.hs#L33 are deemed ready for public consumption in GHC 7.8.1, and can be registered with upstream Cabal now (maybe even for the upcoming 1.18.0 release)? Related: http://ghc.haskell.org/trac/ghc/ticket/8176 Cheers, hvr

Good question. Here's the list with my comments. We need input from Ian. on
RelaxedLayout AlternativeLayoutRule AlternativeLayoutRuleTransitional I have no idea about these three.
AlternativeLayoutRule* aren't ready. I'm afraid I can't even remember what RelaxedLayout does OTTOMH. Thanks Ian
Ian, is there any documentation of what these three things were doing? A wiki page? If not, should we revert them all out again? We don't want to leave experiments that have no active "sponsor" in the code. On the other hand, you are wanting to pursue it, that's great.

fwiw, here's the commit that introduced it: http://git.haskell.org/?p=ghc.git;a=commitdiff;h=9a82b1ffa35fa4c3927c66a1037... ...and moreover, you disabled it by default in http://git.haskell.org/?p=ghc.git;a=commitdiff;h=1bed452fb7c3b5c55c734920a26...
