   I haven't benchmarked this, but I think likely that there would only   
   be a small difference.  Usually, the front end only takes a small part of   
   compilation time (but there are pathological cases).   
      
   In general, modules are better because of automatic checking.   
   If you want to avoid recompilation cascades, submodules (where   
   you can separate the definition from the implementation) might   
   be worth looking into.

   Not sure what you're asking for.  Can you give an example?
