I swear I just saw something today or yesterday about pathlib vs os.path for parameters.

I have forever done something like:

```
from os.path import isfile
def read_file(file_path: str) -> None:
if not isfile(file_path):
print(f"{file_path} is not a file")
return None
...

```

Which is fine, and returning `None` from there all depends on what you want to happen; should it raise an Exception etc..

So instead of `file_path: str` and passing a `pathlib.Path` or similar would be calling a method on the object itself instead of just calling `os.path.isfile` (or similar).

What am I missing here? Am I trying to be too creative about something trivial?
