# This example illustrates explicit callbacks via Reflex roles. An
# object is assigned a role to play in its owner. Event names are
# mapped to methods by joining a prefix ("on" by default), the role
# name, and the event name. For example, a DNS resolver might have
# the role "resolver". The invocant's on_resolver_answer() would be
# called by default to invoke the resolver's "answer" event.
# Reflex::Callbacks and the Reflex::Callback helper classes will
# abstract callbacks to fulfill a number of goals. The goals are
# detailed in docs/TODO.otl and summarized in eg/eg-20-rcb-callback.pl
