Hi all,
I've added a feature request ticket to the GHC trac:
http://ghc.haskell.org/trac/ghc/ticket/8043
for qualified module exports. In a nutshell this would allow the following 'qualified module' export eg:
module MyModule ( qualified module T ) import qualified Data.Text as T
so that any module which imports MyModule has access to the symbols of Data.Text under the quaified module name T.
This feature actually looks like something which I'm capable of undertaking so if nobody thinks this is a really bad idea, I'll have a crack at this.
There have been discussions about this in the past, here is a good one: http://www.haskell.org/pipermail/libraries/2005-March/003390.html (read the rest of the thread, and there are links in there to other threads). This is a feature that at first seems simple but leads to a lot of subtle issues. And it's not clear (to me at least) that this is something we want rather than some form of namespace-management at the package level. Cheers, Simon
