fun finalize

core :: Finalizable :: finalize

Liberate any resources held by self before the memory holding self is freed

This method is invoked by the GC during a garbage collection when self is no longer referenced. It can also be called by the user. Its implementation must be planned accordingly and ensure that it may be invoked more than once.

The object are not finialized in a topological order, it is safe for this method to use attributes of this instances, unless theses attributes are finalizable as well because they may have been finalized already.
