the Gravity of Python 2

[Martijn Faassen]

Hi,

I've posted a documentation issue to the 'future' module which includes 
a further evolution of my thinking. As I expected, the author of the 
'future' module has thought this through more than I had:

https://github.com/PythonCharmers/python-future/issues/27

To get back to a hypothetical Python 2.8, it could implement this kind 
of behavior, and I think it would help support incremental upgrades. As 
long as you're using Py 3 bytes and str in your code, you'll be aware of 
errors and be forced to think about it. Other Python code in the system 
can remain unchanged, and to the magic of ducktyping will continue to 
work. You can then tackle things incrementally.

Regards,

Martijn
