And it's also nice to know that the author (goldfire) intended for this to happen. Now that I better understand all the actors in this production, I also agree that this behavior is reasonable. The only thing missing from https://git.haskell.org/ghc.git/commit/9a34bf1985035858ece043bf38b47b6ff4b88... was a note in the users' guide. I've opened Phab:D2774 for this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12907#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
