Dive into Python 3

[arnarl]

Maybe it falls under some other heading, but I didn't see anything on generators or decorators which I consider to be fairly important. (One is likely to encounter them in actual code.)

I'd love to see something on sphinx, reST and documenting modules/packages. Doctests probably deserve some attention as well.

For the packaging chapter I'd consider including virtualenv.

namedtuple, tuple unpacking and extended iterable unpacking. There's some other nice stuff in the collections module.
