Comment (by bgamari):

 On the matter of the concrete renaming, I would say that unnecessary
 renaming of GHC's traditional nomenclature should be avoided. That is,
 renaming the desugarer to `HaskellToCore` is in my opinion going to cause
 far more harm than good. These names are scattered throughout commit
 messages, documentation, comments, and the wiki and it's not practical to
 rename them all. While it may be true that the function of the "desugarer"
 isn't immediately clear to newcomers, I would argue that this nomenclature
 is a tiny bit to learn relative to the rest of GHC, and that inconsistent
 naming will make things even harder.
