(3) seems to be working well for the H98 modules; in effect the switch to
hierarchical modules has given us one-off package versioning. The only
problem is that the not-so-hierarchical module Foreign is in the base
package rather than haskell98, and I would argue that such an omnibus
module doesn't belong in the hierarchical libraries, even if it does
make your import list shorter. How about moving it?
