That's up to the Release Manager (Barry this time), but I expect the
introduction of a type-check gimmick alone leaves it no chance (that's a new
direction for Python, so is PEP material unless Guido loves it intensely at
once).

I expect we will.  Ditto __metatype__, long-winded super(), function-based
property "declarations", and all the other new stuff.  We're aiming for
progress with the new features, not perfection <wink>.

The last 2.2 beta should be released before your return.
