I found this:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/a1316cb4e216eba4/0cda739385abd03c?lnk=gst&q=Self-Reproducing+Program#0cda739385abd03c

It contains a lambda-solution similar to mine, only more concise:

(lambda x:x%`x`)('(lambda x:x%%`x`)(%s)')

I have been using python for 7 years, and it the first time ever that
I see the `...` construct being used!  In fact I didn't even remember
that it existed (I'm not even sure that I've ever known about it...)

Thanks
