+`attrs.converters.pipe()` now preserves the return annotation of a final `attrs.Converter` when Python cannot inspect the converter instance's signature, including early Python 3.11 releases.

+Use {func}`attrs.converters.pipe` to apply converters in sequence.
+A final {class}`attrs.Converter` preserves the return annotation of its wrapped function.
+Tools can inspect that annotation on the pipeline:
+
+```{doctest}
+>>> import inspect
+>>> from attrs.converters import pipe
+>>> def to_int(value) -> int:
+...     return int(value)

+>>> inspect.signature(converter.__call__).return_annotation

 Or as a decorator
