I've thought of that, and it is tempting. However, it does not give
you any clue what the decorator actually *does*, that's why I don't
like it. People would declare any decorator using @decorator, without
thinking whether they actually need to make that declaration. By
design, any function (or, any callable for that matter) can serve
as a decorator, so having a declaration for it might actually add
confusion.
