I disagree.

I remember this "issue" with decorators as well.

@property
def foo....

@lru_cache()    # really?
def bar...


All decorators created with context_manager have this behavior. The 
proposal is about removing () for function definitions, so this differs.

However, decorators have a very declarative style as do function 
definitions. So what do those special characters serve?

IMHO It's just visual clutter.

Best,
