Having thought about this some more, it seems we have enough __dunder__ 
attributes that are plain strings that having this one also be a plain 
string should not be a problem:

- __name__
- __module__
- __file__

Since Paths are immutable the __os_path__ attribute isn't going to 
change and doesn't need to be a method.
