decorator may not be defined as a class property

sorry for asking dumb question, but what is the specific reason for defining method decorator inside a class like this https://github.com/lavagetto/python-etcd3/blob/5ca831bf8695d2c0e8e50a86a07290e7f1a04479/etcd3/client.py#L293?

why not define a standalone function instead?

Read etcd3/client.py around line 293 and inspect how the method decorator is defined and used within the client class. Determine whether the issue calls for a standalone function or only an explanation of the existing design; done means reaching and documenting a clear decision, with any affected uses identified.
