Today is the day to get in those Py3K PEPs. In order to meet a sometime-in-June alpha for Python 3.0, a deadline for PEPs specifically affecting the release are due today. The only exemption is that of PEPs and such affecting the stdlib.
This week has already seen a flurry of new PEPs come in. PEPs 3121, 3122, and 3141 have been checked in. Plus there are roughly three or four currently being discussed on python-3000. The only benefit of all of these PEPs being out in the wild is that people are actually focusing their discussions and not going all over the place as tends to happen when there is debate over only a single PEP.
