Technically, as soon as we start using python 2.6 syntax, the file won't parse
anyway.

Feel free to set the CQ bit when you think it's fine to do. We need someone to
be present for some hours (?) after in case there's one slave on a unknown
master that is broken. I looked at all macs on m1 and m3.

The sooner the better.

Looks fine to me. 

In webkit, I solved this by having the code in a module that gets imported at
the beginning of the file; that way you error out before you even potentially
import other modules that might use incompatible things (e.g., with statements
on 2.5).

See, e.g.:
