How about something that can't be done with a function, such as the
functionality of the "with" statement that was added to python 2.5?

Yes, it has to handle a suite of statements.

It would be nice if it handled both the "{as target}" and no target
forms.

Also, it shouldn't rely on magic names - if it needs a variable for
its purposes, it should guarantee that said variable and/or use can
not be one that affects how the rest of the user's program behaves.

There's a fair amount of relevant discussion in http://www.python.org/dev/peps/pep-0343/
