Comment (by iampure at gmail.com):

 In the following code with Foo a class name(i.e. class Foo x y zwhere...)
 that is is imported from another module:

 {{{a = $(do info <-  reify (Name (mkOccName "Foo") NameS)
          () <- trace (show info) (return ())
          (liftM (LitE . StringL) currentModule))}}}

 The problem is that whatever I try, I don't get an info value. I basically
 guessed the NameS constructor, since I don't know what the "S" stands for.

 So, the problem is getting access to the Info value. I am either reifying
 the wrong thing or this feature simply does not work.
