The answer is that they are to be separated from GHC and put into another package, in accordance with the final goals of Trees that Grow. (See Note [Trees -that grow] in 'Language.Haskell.Syntax.Extension'.) - -We cannot separate them yet, but by giving them names like so, we hope -to remind others that the goal is to factor them out, and therefore -dependencies on the rest of GHC should never be added, only removed. +that grow] in 'Language.Haskell.Syntax.Extension'.) In short, the +'Language.Haskell.Syntax.*' tree should be entirely GHC-independent. +GHC-specific stuff related to source-language syntax should be in +'GHC.Hs.*'. + +We cannot move them to the separate package yet, but by giving them +names like so, we hope to remind others that the goal is to factor them +out, and therefore dependencies on the rest of GHC should never be +added, only removed.
