References
References are globally unique Erlang
terms. They are created with the BIF erlang:make_ref().
References are useful for creating unique tags that can be
included in data and then at a later stage compared for
equality. For example, a bug-tracking system might add a reference to
each new bug report in order to give it a unique identity.
