I can certainly agree with the opinion that raw strings are working as 
documented, but I can also agree with the opinion that they contain traps for 
the unwary, and after getting trapped several times, I have chosen to put up 
with the double-backslash requirement of regular strings, and avoid the use of 
raw strings in my code.  The double-backslash requirement of regular strings 
gets ugly for Windows pathnames and some regular expressions, but the traps of 
raw strings are more annoying that that.

I'm quite sure it would be impossible to "fix" raw strings without causing 
deprecation churn for people to whom they are useful (if there are any such; 
hard for me to imagine, but I'm sure there are).

I'm quite sure the only reasonable "fix" would be to invent a new type of 
"escape-free" or "exact" string (to not overuse the term raw, and make two 
types of raw string).  With Python 3, and UTF-8 source files, there is little 
need for \-prefixed characters (and there is already a string syntax that 
permits them, when they are needed), so it seems like inventing a new string 
syntax

e'string'
e"""string"""

which would not treat \ in any special manner whatsoever, would be useful for 
all the cases raw strings are presently useful for, and even more useful, 
because it would handle all the cases that are presently traps for the unwary 
that raw-strings have.

The problem mention in this thread of escaping the outer quote character is 
much more appropriately handled by the triple-quote form.  I don't know the 
Python history well enough to know if raw strings predated triple-quote; if 
they didn't, there is would have been no need for raw strings to attempt to 
support such.
