because

  (1) it is arbitrary restriction
  (2) it has a *very* very different meaning.  It modifies
       name lookup -- the original poster did NOT intend to dump
       everything in the current scope.

I'm amazed at seeing the proposed resolution.  I suppose
I have to raise that at the next meeting.
