# Encapsulation of service in a `for`-compatible interface.
#
# The service is not effectively started until the iterate method
# is called. Then, each step of the iteration is a step in the service.
#
# While, for a typing point of view, abusers are just classes with an
# iterator method, the point of this class is to tag services that return
# a ForAbuser object.
#
# Note that using having `ForAbuser` as a genuine subclass of `Collection`
# works but is not recommended since it may cause mental health issues.
interface ForAbuser[E]
	# Starts and control the service
