The intent of my post was to say that all of us want Py3k to succeed, I should hope that we all do.

but I believe that in order for it to succeed that breakage from the 2.x series should be gradual, in a similar way to how 2.x -> 2.x+1 breakage has been gradual. Given that the rate of intentional breakage in the core language (including builtins) has been very minimal, this would take a couple of decades, which to my mind would be a failure. If we could stick with a 12-18 month release schedule, using deprecation and removal in subsequent releases, every removal could happen in 2-3 years. 2.6 could offer every feature of 3.0 (except for backwards-incompatible syntax), warning of removal or relocation (in the case of stdlib reorganization), 3.0 could handle all of the actual syntax changes.

2.6 should also include a powerful 'lint' option that detects use of features not compatible with 3.0. Something like "from future import pedantic" or something along those lines.
