+types in an uniform manner, regardless of their underlying implementation.

+Currently supported types are:
+@itemize
+@item scrapy.item.Item
+@item dict
+@item dataclass-based classes
+@item attrs-based classes
+@item pydantic-based classes
+@end itemize
+
+Additionally, interaction with arbitrary types is supported by
+implementing a pre-defined interface.")
