What do we think about `length :: [_] -> Int`?
No, this is not a use in a ''type pattern'' (as are all they cases discussed above). It's an occurrence, pure and simple. This is explicitly covered by `PartialTypeSignatures` and I don't want to change all of that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11451#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
