Ah! this makes more sense, the idea of persistent properties even fits with this idea, though a true write-in-place property might be even better for some applications ;)

Two things: * Don't count on storing the hit counter as a separate, "persistence aware" object (i.e., with its own pickle jar) to avoid bloating your Data.fs. Hit counters are by definition high volume, and the space overhead for managing undoable persistence is higher than you might think. * Write-in-place will never be supported by packable/undoable storages (logically impossible); some "packless" storages are already in play (maybe even near release), so the semantics you want may be (soon) readily available by mounting a separate storage.
