   We record location information during expression evaluation.  However, we don't
   store the line numbers of where the data was inserted or updated
   in the {@link net.sourceforge.mayfly.datastore.DataStore} itself,
   because they wouldn't make any sense without also including a stack trace of
   where they were created (and perhaps other information like filenames), 
   and it is far from clear that
   the information would be particularly helpful.
