As an aside, I don't see why this would require anyone to change their 
code.  So long as people choose good module names, the movement of some 
module from one package to another at most changes a Makefile or .cabal 
file.  I actually rather like this about Haskell as it currently exists; 
third-party packages don't have to be isolated behemoths walled off by 
namespace issues.  In fact, there are good examples of cases where 
external packages define modules in Data.* module hierarchy with 
perfectly logical names.  The code is then entirely independent of 
packaging concerns.
