Independent of TDNR I would welcome this. Maybe Ticket 2551 ("Allow multiple modules per source file") [1] should be reconsidered.
Although ticket 2551 is not exactly what Luke is suggesting (which would be an extension to the language, whereas, if I'm not mistaken, 2551 is just a change to where GHC can find modules, not nesting of modules).
