[Pharo-project] Should a serializer do something in particular with weak references?

Hi guys. Martin and I were discussing whether we should do something in particular in Fuel with Weak references, such as WeakArray. Should we serialize it the same way we serialize all objects, or should we do something special? what could be the impact of materializing such weak references in a new image for example? Thanks your sharing your thoughts. -- Mariano http://marianopeck.wordpress.com
