Well, my intention is for it to begin right after 3.1 was released.
While the time machine can do stuff with SVN or Hg branches, it's not
powerful enough to mess with code already released.

Though honestly I don't recall exactly what was added between the with
statement and the 3.1 release apart from 'nonlocal'.
