This discussion made me realize that the various Babel backends may have different approaches wrt evaluating blocks, returning output and results, interpreting empty output/result, etc. The mere notion of a "session" may differ from one language to another. I wish we can push for more consistency here--perhaps the first stop would be (1) to pick major backends and (2) document their behaviors. I'm sure this could help enhancing Org babel code too.
