With the most recent update to [haskell] things are looking a little
bit better, but we're not quite there yet.  At the moment I'm
performing a fairly naive check and quite possibly a more detailed
look will show that the move is already possible.  I'll try to have a
look at that during this week.

Unfortunately I don't have to current list of breakages readily
available (it's on my laptop at home).
