I think "technical merit" includes whether a feature has consistent
behavior.  I consider the current binding system to be consistent.  You can
mis-use it, but for any given expression, it will evaluate correctly.  This
proposal, if it includes expressions with variables, introduces timing
dependencies.  I think that is a technical flaw.
