*Slightly* related question. Sorry for the tangent.

In Python 3K, when the string data-type has gone, what will
``open(filename).read()`` return ? Will the object returned have a
``decode`` method, to coerce to a unicode string ?

Also, what datatype will ``u'some string'.encode('ascii')`` return ?

I assume that when the ``bytes`` datatype is implemented, we will be
able to do ``open(filename, 'wb').write(bytes(somedata))`` ? Hmmm... I
probably ought to read the bytes PEP and the Py3k one...

Just curious...

All the best,

Michael Foord
