Is there a JIRA about defining a e.g. Flatbuffers-based serialization protocol (probably better than Protobuf so we avoid having to introduce a library dependency) for expressions? Seems like it might provide a more scalable solution for serialization and could eventually succeed the strategy here |

The Scalar are not properly exposed yet and the C++ implementation will change soon so while the serialization will work, we need to refactor this code.
