All 2.2 for-loops (whether or not in list comprehensions) use the 2.2
iterator protocol; this is 100% backward-compatible with 2.1's __getitem__
protocol.

Lots of the new stuff isn't even mentioned in the docs yet.  Per-attribute
getter/setter/deleters are described in Guido's tutorial, though:

    http://www.python.org/2.2/descrintro.html

Look for "property".
