I think we'll need to keep the function-argument restriction to avoid confusion around laziness
When you say "confusion around laziness", are you referring to difficulty the user would have with reasoning about the behavior of a functions, or are you referring to an inability of GHC to generate correct code in this situation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15532#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
