What would be the actual change proposed? If it is something concrete

good. I have enough issues with the layout rule as is :)
I imagine it would be something like deleting the production
lexp6 -> - exp7
and adding the production
exp10 -> - fexp
Remember that Haskell 2010 changed things here, so that production no
longer exists:
http://hackage.haskell.org/trac/haskell-prime/wiki/FixityResolution
the equivalent change can be made in the new formulation, of course, and
would probably simplify it.
Cheers,
