what is wrong with that r"\"

May I suggest giving the possibility to use any delimiter for a raw string?  just like in Vi or ruby.

Vi:
 %s_a_b_g  is valid and so is  %s/a/b/g

Ruby:
 %q{dj'\ks'a\'"}   or %q-dj'\ks'a\'"-

So as long as your regex does not use all the valid characters, readability is maintained.

Where's the problem!? ::

  re.compile(r''''"''')

Ah, I see -- readability is the problem.  :-)
