I'd appreciate a few more eyes over this, in particular look out for
messed up typesetting as there could still be a few bugs lurking.

In the PDF:

p129-137: A "program" can only contain a "modid" as part of a
           "qvarid", ..., "qconsym", but e.g. a "module" needs a
           bare "modid". May be best to defer fixing this, and
           tidy up the syntax definition in H2011.

p152: There's a huge amount of whitespace between "dclass" and "inst"

p153: Same "guard  -->   pat<- infixexp" comment as on p37 (GHC bug?).
p153: Same "guard  -->   infixexp" comment as on p37 (GHC bug?).

p153: RHS of "gdrhs" production should be purple (as on p66)

p154: As on p42, the negative literal alternative in pat is redundant

p156: The argument to resolve doesn't have to strictly alternate, e.g.
       "id $ - three".

p156: The program needs an "import Control.Monad"
p156: The program should derive Show for everything

p157: In one case (in the penultimate paragraph) "-" is quoted and short,
       while earlier uses are bare and long.

All fixed, thanks.

p159: Is this legal?:
           {-# LANGUAGE EmptyDataDecls #-}
           data Foo
               deriving ()
       GHC accepts it, but hugs says (unexpected keyword "deriving")

Yes, it's legal according to the grammar.

Cheers,
        Simon
