thanks James!

Never really noticed this possibility in the manual. Good to know and interesting to use.

PassiveObject starts with a root object and traces through its instance variables, and their instance variables, recursively until it reaches special objects (instances of SmallInteger, Character, Boolean, SmallDouble, or UndefinedObject), or classes that can be reduced to special objects (strings and numbers that are not integers), creating a representation of the object that preserves all of the values required to re-create it. The resulting network of object descriptions can be written to a file, stream, or string."
