I can't understand why we can't have a new keyword for decorators. If I remember correctly the introduction of yield didn't result in such a public outcry. We'd have to change our programs once if a variable names collides with the new keyword, but that's better than having to look at @s for the rest of our Python days.

Not such a large outcry, but lots of us were concerned about "having to look inside the function for 'yield' to determine if it were a generator or a function" and were calling for a 'gen' or 'generator' keyword.

Strangely enough, exactly the opposite argument is now being used to prevent syntaxes such as:

def func (args):
    @decorator

as was used then to allow:

def func (args):
    yield value
