Right that is the V2 paradigm as well (although it doesn't make as much use
of helper classes as I would like).

It's my major worry point.  My feeling is that we will end up with ugly code
_somewhere_, either in the parsers or in the actual code that does the work.
Since I am writing the latter right now you can guess where my preference
lies right now...
