Okay, that makes sense. But we agree that when writing paths as string
literals, you should (nearly) always use forward slashes in Python.

Why not raw strings? Because raw strings aren't actually fully raw, and
consequently they don't allow the string to end with a backslash:


py> s = r'documents\'
  File "<stdin>", line 1
    s = r'documents\'
                    ^
SyntaxError: EOL while scanning string literal


(I still don't understand why this isn't just treated as a bug in raw string
parsing and fixed...)
