Avoiding class decorators

If we recall the class decorator we used in Chapter 5, Using Decorators to Improve Our Code, to determine how an event object is going to be serialized, we ended up with an implementation that (for Python 3.7+) relied on two class decorators:

@Serialization(    username=show_original,    password=hide_field,    ip=show_original,    timestamp=format_time,)@dataclassclass LoginEvent:    username: str    password: str    ip: str    timestamp: datetime
