Things to check first

I have searched the existing issues and didn't find my bug already reported there
I have checked that my bug is still present in the latest release

Typeguard version

4.1.2 (archlinux repo) and 4.1.4 (pip)

Python version

Python 3.11.5 (main, Aug 28 2023, 20:02:58) [GCC 13.2.1 20230801] on linux

What happened?

How can we reproduce the bug?

import io
import typeguard
import typing


@typeguard.typechecked
def test_bug(buffer: bytes) -> typing.Callable[[int], bytes]:
    return io.BytesIO(buffer).read
