I've conferred with Alex on this request.  Since the JSR 294 expert 
group is working on adding a "module" accessibility level to the 
language, that group is in a good position to weigh the pros and cons of 
adding an explicit "package" modifier at the same time, a change they 
are considering.  Therefore, Project Coin should defer the decision on 
an explicit package modifier to the JSR 294 expert group.
