The `pathlib.Path.home()` function looks like:

    @classmethod
    def home(cls):
        """Return a new path pointing to the user's home directory (as
        returned by os.path.expanduser('~')).
        """
        return cls(cls()._flavour.gethomedir(None))

If we add a `username=None` parameter and pass this to `gethomedir()` we can easily add a lookup of another user's home directory, so:

    import pathlib
    username = 'phil'
    pathlib.Path.home(username) == pathlib.Path('~' + username).expanduser()
