I'm an experienced Perl developer learning Python, but I seem to
be missing something about raw strings. Here's a transcript of
a Python shell session:
Python 3.0 (r30:67507, Dec 3 2008, 20:14:27) [MSC v.1500 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

IDLE 3.0
>>> r"a\b"
'a\\b'
>>> r"a\"
SyntaxError: EOL while scanning string literal (<pyshell#45>, line 1)
>>> r"a\ "
'a\\ '
>>> r"a\""
'a\\"'
It seems the parser is interpreting the backslash as an escape
character in a raw string if the backslash is the last character.
Is this expected?
