Summary: r'\' => Syntax error

Initial Comment:
The raw string is supposed to treat \ as literal
characters. It does that with

>>> print r'\aslkjv'
\aslkjv

and

>>> print r'\'kdsr'
\'kdsr

but not with

>>> print r'\'
  File "<stdin>", line 1
    print r'\'
             ^
SyntaxError: invalid token

In the last case, I intend to have a string containing
a \ only.

This happens with Python 1.5.2 and 2.1.1
(on FreeBSD and/or Linux)

Sorry, you're out of luck -- raw strings can't end with an odd 
number of backslashes, else there would be no way to write 
a raw string containing the quoting character.  See FAQ 
entry 6.29:
