I will look at squeak stuff. But my question more about about conceptual problem: I need week dictionary which values has reference to it key. Can it be really week? I think it can be kind of "ephemeron problem" and such dictionary contents will never be garbaged. Is ephemerons supported by latest vm? In pharo I see two classes: WeakKeyDictionary and WeakValueDictionary. What you think I should use to implement my requirements: cache which can be cleaned by garbage collector due to weak keys or values? 2012/11/27 Stéphane Ducasse <[email protected]> > Ghost I think it is just implementation of very skin proxy objects? Is it related to weak dictionary cache?
