Comment (by bgamari):

 > Yes it is! We typecheck the module before generating those extra
 bindings.

 Hmm, in that case I'm a bit stumped as to why my `wip/typeable-unwired`
 branch fails while building `GHC.Types` with,

 {{{
   libraries/ghc-prim/GHC/Types.hs:1:1: error:
       GHC internal error: ‘TyCon’ is not in scope during type checking,
 but it passed the renamer
 }}}

 This appears to occur at some point between the `Tc3` and `Tc4` trace
 points.
