Yes, that all sounds like a good idea. I think changing some "strings" to
b"strings" is a necessary step on the way to 'python -U'. 

I would want to avoid the need for a 2.0-style 'default encoding', so I
suggest it shouldnt be possible to mix this type with other strings:

>>> "1"+b"2"
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: cannot add type "binary" to string
>>> "3"==b"3"
