I remember this "issue" with decorators as well.
@lru_cache() # really?
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.
