Subject: Remove special lambda unicode character, it didn't work anyway
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=866316bd1fd56d4f122e550b14cc3c0d894e28ba

Remove special lambda unicode character, it didn't work anyway
Since lambda is a lower-case letter, it's debatable whether we want to
steal it to mean lambda in Haskell source.  However if we did, then we
would probably want to make it a "special" symbol, not just a reserved
symbol, otherwise writing \x->... (using unicode characters of course)
wouldn't work, because \x would be treated as a single identifier,
you'd need a space.
