{-# OPTIONS -package foo #-} -- or replace with myfoo module F where import Foo
No, I think you missed the point. Let's say there are 30 files that import modules from the package "foo". At the moment, and with the current proposal, when you decide to replace "foo" with "myfoo", you must edit all 30 files to change the OPTIONS line (or the "import from" specs).
This is a red herring, you could use a proxy module with either option (and in the example you quote, I meant to re-export Foo of course. Sorry.) Or, you could use a global command line instead of local pragmas/import modifiers. As I understand your proposal at http://cvs.haskell.org/trac/ghc/wiki/GhcPackageNamespaces , the main contribution from namespaces is to introduce an intermediate level between packages and modules. (Which of course is useful when the packages encompass a lot of functionality.) -k -- If I haven't seen further, it is by standing in the footprints of giants
