    Tuple returns do seem trickier than multiple arguments, partly due to
being more novel for me and partly because the function definition does not
document the tuple in code, although there is often a comment. Perhaps
something like:

def Transform(filename) -> (share, permissions, lock):
...
    return (s, p, l)
...
(s=share, p=permissions) = Transform(name)
