Draft:

class List:
    def users(self, name: str = '') -> typing.List[User]:
        """
        .. http:get:: /api/lists/(id)/users?name=

           Query users who interacted with the list and (partially) match *name*.

           *name* defaults to an empty string, matching all users. A maximum of 10 items is
           returned.
        """

# Acquaintances (future reference)

class User:
    def acquaintances(self, name: str = '', context: List = None) -> typing.List[User]:
        ...
