Decorators will add complexity, regardless of syntax.

Especially in their current over-powered form. If decorators didn't have to take arguments, then you could use a syntax like:

def classmethod foo(cls, ...): ...

This does add complexity, but I think it enhances understandability.

I understand why some people want to be able to pass arguments to decorators, but frankly, I find many of the examples of doing so down right scary.

An advantage of the @ syntax is than it makes the complexiity separable and ignorable for someone learning/teaching basic Python,

I don't agree that they are ignorable. People will see them in code and will have to understand what they mean. Given sme examples I've seen here, this will sometimes be a significant chalenge.
