I looked at Neman Cells. It looks like a pretty straightforward implementation of the observer pattern. I only took a quick glance, but I see nothing that would handle circularity. The async cells look to me like one could have an inconsistent view of the data depending on *when* one looked at the cells. This is fine, I suppose, for some purposes, but I'd prefer something more deterministic. Plus I'd prefer less state rather than more. When I finish my Datalog work, I'm thinking of leveraging some of that knowledge to build a dataflow declarative computation framework similar to Cells, using explicit parallelism rather than asynchonisity.
If anyone knows of this mysterious "one more implementation", I'd love to see it. Thanks.
