says about Fuel

- No special VM-support needed.
- Can serialize/materialize not only plain objects but also classes,
traits, methods, closures, contexts, packages, etc.
- Very customizable: ignore certain instance variables, substitute
objects by others, pre and post serialization and materialization
actions, etc.
- Supports class rename and class reshape.
- Good test coverage (almost 600 unit tests).
