Except that makes the decision the thrower's, rather then the [non-]catcher's.

For example, "use warnings 'none'" could become 
"$Exception::warnings::uncaught_handler = undef" under my proposal, but
isn't doable under yours.  Basicly, my idea would let you specify exception
handlers, or use try{}catch{} (-ish) structures, giving try/catch first
chance.
