OK, so if all paths can be represented as strings, why don't we just make `pathlib.Path` subclass `str`? Well, as I said earlier, not all strings are paths. You can't concatenate a string representing a path with some other random string and expect to get back a string that still represents a valid string
I assume you mean a valid path.
You can't add an int to a float and expect to get an integer back, either. If you're adding it to a random string you're clearly not using it in a path context, and the type of the result won't be Path anyway.
