Quite right. And it works with the new parser.

The new GHC lexer contains some small bugs:
-- Foo.hs
module Foo where
forall :: Int
forall = 1
-- Main.hs ---
import Foo
main :: IO ()
main = print forall

In the processing of compiling GHC 4.02 using the *.hc files
recently made available, in a RedHat 6.0 (glibc 2.1, egcs 1.1.2),
I have executed the commands:
$ cd /var/tmp
$ tar -zxf /urano/downloads/haskell/ghc/ghc-4.02-src.tar.gz
$ cd fptools
$ tar -zxf /urano/dow
