Hi Pedro, You are right, it is a partial implementation. We chose not to propose an implementation for associated datatypes and type families because it is unknown if there is a demand for it. But I don't think coming up with the TH AST modifications for associated type synonyms and type

Hello Thomas, I see this is a proposal for a partial implementation of #1673 ( http://hackage.haskell.org/trac/ghc/ticket/1673). Maybe it would be good if the remaining syntax (associated datatypes and type families) would also be defined and implemented in TH. Or maybe there isn't much demand

Hello, Recently, we released a library on Hackage for generic rewriting (package rewriting if you are curious). The user of the library is expected to define type class instances to enable rewriting on his or her own datatypes. As these instances follow the datatype declarations closely, we
