Zuhair, this is the kind of thing I tell you about all the time: You
don't start with a high level, intuitive set of examples of what your
latest proposal for a system (leaving its predecessors by the wayside
in a heap) is attempting to do or represent. And I tell you that it
makes it harder for anyone to contribute and so you get questions
about what you really mean - and you just refer him to someone else's
work. But if this has already been proposed and written about, why
repeat it here? You say it's too time-consuming to explain it, but
spend time dealing with the people who ask you piecemeal what I said
you left out.
