        Hi
Give the following code below, my question is - how do i setup a dependency of User on Common?
Perhaps a first attempt should not have Common store a reference to User, nor User store a reference to Common. Instead, have two Data.Map.Map's: one looks up from Common to User, one from User to Common.
Sounds like a bidirectional Map to me - fortunately hackage already has one of these: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bimap Thanks Neil
