I think it might be simpler just to say {{{ {-# NO_WARN_REDUNDANT_CONSTRAINTS singleton #-} }}}

I would not like to let the type checker ignore all redundant constraints at once in a signature. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10635#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
