Stef,

I haven't completely wrapped my brain around what SnapshotCello does so I don't have an informed opinion ... the fact that you found a need to invent SnapshotCello does speak volumes to the fact that there is a need that is going unmet:).

What is not clear? I would be interested in describing our scenario in more details because I think this is a development pattern. But, I need some concrete questions to start from.

However, I don't like the fact that you end up sending a non-spec message to make this work (#populateSpec:with:). Tools like Versioner will not be able to rewrite a method like this correctly so it is a less than satisfactory workaround to the method literal limit.

I still do not understand why Versionner would be affected by the current versions given that we are only generating versions that should be immutable hence no need for management.

With that said it _is_ performing a useful function ...

I have recently come up with an approach to addressing the method literal limit from a slightly different angle and I would assume that SnapshotCello could be recast to use this "approved approach" when the new techinique becomes available. At that time it would make sense to roll the SnapshotCello funtionality into the MetacelloToolBox...

Having a different way to store the information should be no problem. I am curious about your ideas.

Cheers, Doru

Dale
