I share many of your fears, but I personally don't see how Python 3 and 2 
could be possibly compatible. There quite some basic changes, e.g. the format 
specifier (print "Hello %s" % "World") does not exist any more, strings are 
unicode etc.

And if Guido abandons these changes, then I don't see much sense in Python 3.

My hope is that the code can be made compatible in a way, so that the 
resulting code of the Python 2->3 conversion is running. There would be 4 
versions available, true, but the Python3 versions could be generated 
automatically.

Best Regards,
Hermann
