Simon and I have been thinking about fixing this, and we think we might
actually do so for GHC 6.6. Your message provoked us to write up the
design. It's here
http://hackage.haskell.org/trac/ghc/wiki/GhcPackages
Feedback welcome
It's worth reading the old threads; for example
http://www.haskell.org//pipermail/libraries/2005-August/004281.html
But there are many others!

| Hi -
| At the moment there is a problem in that two packages P and Q could
contain
| the same hierarchical module eg Data.Foo, and the only way for user
code to
| ensure the "right" Data.Foo is used is to ensure that packages P and Q
are
| searched in the right order.
| However suppose P and Q also contain another module with the same
name, eg
| Data.Bar.
| And suppose a user module wants to use Data.Foo from P but Data.Bar
from
| Q!!!
