ur'foo' syntax under Python 3

[Lele Gaifax]

Hi all,

I'm using Python 3.3, and I was surprised to realize that it does not
support the old Python 2 syntax ur"literal-raw-unicode-strings".

Is there any trick to write such literals in a Python2+3 compatible
source?

Is there a rationale behind the invalid syntax or is it just a glitch?

thanks in advance,
bye, lele.
