Comment (by simonpj):

 Yes, we could certainly provide a way to get the current package.  I don't
 know if that would serve this current use-case, but it's a good idea
 anyway.

 The best way to do that would be to elaborate `qReifyModule`, which
 currently returns a `ModuleInfo`.  The latter is just
 {{{
 data ModuleInfo =
   -- | Contains the import list of the module.
   ModuleInfo [Module]
 }}}
 but it should really contain the current `Module` to:
 {{{
 data ModuleInfo =
   -- | Contains the import list of the module.
   ModuleInfo { mi_this_mod :: Module
              , mi_imports  :: [Module] }}}
 }}}
 Remember that `Module` is
 {{{
 data Module = Module PkgName ModName
 }}}
 so you can get the current `PkgKey` from the `Module`.

 Someone just needs to work carefully through the new API.
