And I am increasingly dubious about comment:1 and comment:2, which suggest that `kk` should be in scope in the pattern. I can't make sense of that.
I'm not sure how you came to that conclusion. I'm suggesting the opposite—`kk` (from the type signature) should //not// be brought into scope over the body of `SS`! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14498#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
