[Pharo-users] implementing #release in a domain object

[Paul DeBruicker]

Lets say I'm modeling a navy that is comprised of many ships each with
their own soldiers and jobs.  If I want one of the ships to be GC'd do I
need to implement #release in the soldier and job objects and send it to
each of those soldiers and jobs that live and work on the ship I want
GC'd or is removing the references between the ship and the navy enough
to have the whole ship (including its soldiers and jobs)  GC'd?
