class_docstr: Converter base class to be reused by various converters.
  Converter allows one to convert data from various source types to a particular
  destination type. Each source type needs to register its converter. The
  registration for each source type is valid for all descendants of that type.
code: def _do_register(cls, from_type: Type, converter: Any):
      cls.registry[from_type] = converter
