Thanks! It may be a dark corner today. However, if my proposal to add type signatures to pattern synonym builders ends up going through with the committee-requested restriction to allow the signatures to vary only in constraints, I think we'll likely see more such code as people hack around the restriction. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13752#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
