If you give the module a new name in the new package then the old module can re-export all of the symbols in the new module.
In GHC I don't think there is a way for two packages to export the same module and have them be recognized as the same thing, as far as I know.
Right, but you don't have to rename the module if you use the PackageImports extension. (Incidentally, this used by the haskell2010 ibrary, which is implemented in terms of base) http://haskell.org/ghc/docs/latest/html/users_guide/syntax-extns.html#packag... So the following should work, assuming 'original' is a package exporting the Foo.Bar module. {-# LANGUAGE PackageImports #-} module Foo.Bar (module Original) where import "original" Foo.Bar as Original Best regards, Bertram
