Comment (by simonpj):

 I'm utterly lost.  To understand what is proposed here I need a lot more
 specifics and examples.  For example
  * I think (though you do not say) that clients of the language extension
 would abandon all use of the `template-haskell` library.  Instead they
 would depend on the `ghc` library.
  * I think that `[| e |]` would have type `Q (HsExpr RdrName)`.
 Etc etc.  But it needs fleshing out or we'll all just talk at cross
 purposes.
