Does anyone know if they diverged in functionality/semantics? If not, would it be a useful step to migrate GHC's `Doc` to annotated version?
In #10735, I made GHC's copy of `pretty` pretty much the same as pretty-1.2.0, except GHC's copy uses `FastString` instead of `String`. pretty-1.2.1 has 2 more commits, but I didn't apply them because of performance worries (`compiler/utils/Pretty.hs` is incredibly performance sensitive!), see ticket:10735#comment:23. Right after pretty-1.2.1, those annotations were added. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8809#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
