Here is another interesting one I typed interactively.

x=r"""\
... """
#>> x
'\\\012'
#>>> 

To me the r'' syntax is inconsistent and works 99% of the time only.
I don't want to check if there is a BS at the end of a string and do
some magic to fix it. The r'' should be doing that for me. 

The big problem comes not when you are coding (cause you can see the
literal yourself and fix it) but when we generate Python scripts on
the fly especially in HTML pages.

I just don't understand why the parser can't be smart enough about
this.
