TODO.md

• err_at!() to include backtrace if available, review all errors.
• Instead of custom Error try to use one of the stdlib error.
• Implement a command line tool to serialize cbor value into bytes and deserialize them back and render their shape and content on terminal.
• Double check the requirement for log package. Should we log or just return errors ?
• Implement Diff for basic-types: array, slice, string, Vec, tuple.
• Implement NoDiff as procedural macro on any value struct or enum.
