Comment (by ezyang):

 I suppose not; it is only related. An example is the `NameG` constructor:

 {{{
 Prelude Language.Haskell.TH Language.Haskell.TH.Syntax> :t NameG
 NameG :: NameSpace -> PkgName -> ModName -> NameFlavour
 Prelude Language.Haskell.TH Language.Haskell.TH.Syntax> :info PkgName
 newtype PkgName = PkgName String
         -- Defined in `Language.Haskell.TH.Syntax'
 instance Eq PkgName -- Defined in `Language.Haskell.TH.Syntax'
 instance Ord PkgName -- Defined in `Language.Haskell.TH.Syntax'
 Prelude Language.Haskell.TH Language.Haskell.TH.Syntax> :info ModName
 newtype ModName = ModName String
         -- Defined in `Language.Haskell.TH.Syntax'
 instance Eq ModName -- Defined in `Language.Haskell.TH.Syntax'
 instance Ord ModName -- Defined in `Language.Haskell.TH.Syntax'
 }}}

 So, the suggestion is that with a unified reflection API, it would make
 sense to make TH also accept this information. But maybe this is just a
 separate concern!
