It's not documented in the manual and there are no examples on the linked wiki page or in the mailing list archives. The patch replaces a bottom with an empty list. So it's certainly an improvement :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8431#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
