I'm a little lost now. It looks like `pretty` already has the annotations proposed in comment:3. So is #10735 really all that's left to allow annotations within `SDoc`s?
And I remember somewhere that color would be impossible without a design
That is pretty much right. like comment:3... and yet we have color now.
Well this isn't quite true. Yes, we have color, but I think part of the initial suggestion was to make much greater use of color throughout the message. For instance, we might render the type `Int` in one color and `String` in another, or perhaps render all types in one color and all expressions in another. For this we need more rich semantic content within the message so we don't need to bury the details of error message styling deep inside the compiler. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8809#comment:57 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
