Line 4:
:"As a [[Vardo (Romani wagon)|gypsy wagon]] or a [[poltergeist]] appears and disappears mysteriously, so does this short lived object. As a consequence the code is more difficult to maintain and there is unnecessary resource waste. The typical cause for this antipattern is poor object design." <!-- I think this is a quote -->
A poltergeist can often be identified by its name; they are often called "manager_", "controller_", "supervisor", "start_process", etc.
Sometimes, poltergeist classes are created because the programmer anticipated the need for a more complex architecture. For example, a poltergeist arises if the same method acts as both the ''client'' and ''invoker'' in a [[Command pattern]], and the programmer anticipates separating the two phases. However, this more complex architecture may actually never materialize.
