At first sight it seems to me that it's pretty straightforward to 
translate print(foo) to print2(foo) once "2to3" has done its job.

It looks your main issue is that you're complaining that Python 3000 is 
going to break things in a non-backward compatible way. If you want to 
change that, you're going to be fighting an uphill battle, as this quote 
from PEP 3000 illustrates:

"We need a meta-PEP to describe the compatibility requirements. Python 
3000 will break backwards compatibility. There is no requirement that 
Python 2.9 code will run unmodified on Python 3.0.

I'm not sure whether it is reasonable to require that Python 2.x code 
can be mechanically translated to equivalent Python 3.0 code; Python's 
dynamic typing combined with the plans to change the semantics of 
certain methods of dictionaries, for example, would make this task 
really hard. However, it would be great if there was some tool that did 
at least an 80% job of translation, pointing out areas where it wasn't 
sure using comments or warnings. Perhaps such a tool could be based on 
something like Pychecker."
