Extending Python Syntax with @

Personally, I'd much prefer that we get things like

    def @del

instead of

    def __del__

Save some keystrokes and I think the @ is attention-drawing-enough that 
we don't lose anything. Of course, all it's doing is adding @ to the 
legal characters in a variable name, which might be a waste instead of 
attaching a syntax to it, but...
