Subject: Value expression architecture is now rewritten, but the functionality
 of the old system (for example, the meaning of 'a') has yet to be restored. 
 In the new scheme, this will be done by definition a function outside of the
 value expression logic, rather than the tight coupling between journal
 innards and value expressions that occurred in 2.x.
