Also, this test should also ignore {{{.ghci}}} files because it could alter the prompt. If there are any other tests that do a literal compare on ghci output, then they should all ignore {{{.ghci}}}. Problems will this test will come up in the future if GHCi output changes. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8341> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
