can't find a way around it... maybe a new regression test on this.

work with Python 3.1, 3.2 and up to 3.3.2

Amusingly, it also works in 3.4. |

This broke a lot of our code, I think that priority needs to be raised to urgent. |

my projects are total broken by this, so my temporary solution is to down grade to 3.3.2 somehow we don't have any test to check this before releasing 3.3.3 |

Hmm, sucks. Benjamin, can you come up with a fix? I'll give it a few weeks to wait for more potential regressions and then do a 3.3.4. |

just want to know if there is any tentative schedule to release 3.3.4. the PEP for 3.3 schedule doesn't talk about 3.3.4, so I'm not sure if the decision was to leave latest 3.3 with this broken regression or fix it and release 3.3.4. |
