``` from fileinput import FileInput from pathlib import Path p = Path('.') FileInput(p) ``` Results in: Traceback (most recent call last): File "", line 1, in File "/usr/local/Cellar/python3/3.6.0/Frameworks/Python.framework/Versions/3.6/lib/python3.6/fileinput.py", line 198, in __init__ files = tuple(files) TypeError: 'PosixPath' object is not iterable

You seem to be skipping a step, this is nothing to do with FileInput: >>> [n for n in Path('.')] Traceback (most recent call last): File "", line 1, in TypeError: 'PosixPath' object is not iterable >>> [n for n in Path('.').iterdir()] [PosixPath('build'), PosixPath('install-sh'), ...] Are you proposing a feature that the Path instance should be implicitly iterable for the directory contents?

@arp11 sorry for the too-minimal repro :D - the issue is with FileInput attempting to cast `files` to a tuple. Instead, if passed a PathLike object FileInput should set `files` to a tuple just as it does with a str.
