Comment (by simonpj):

 Generally that seems fine.  But Haskell's namespace control system is more
 complicated than it looks -- see Iavor's
 [https://web.cecs.pdx.edu/~mpj/pubs/hsmods.pdf 2002 Haskell Symposium
 paper] -- so I would urge a careful, clear specification before any more
 implementation happens.
