or

pathA + Path("file.txt")

Just like with any tuple, if you wish to add a new part, it must be a tuple (Path) first.

I'm not convinced that adding a string to a path should be allowed, but if not then we should probably throw a TypeError if its not a tuple or Path. That would leave the following method for appending a suffix:

path[:-1] + Path(path[-1] + '.tar.gz')

That's alot more verbose than the option to "add a string".
