[issue30432] FileInput doesn't accept PathLike objects for file names

[Roy Williams]

Roy Williams added the comment:

@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.

[issue30432] FileInput doesn't accept PathLike objects for file names

Alex Perry added the comment:

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?

[Roy Williams]

New submission from Roy Williams:

```
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
