[Python-Dev] Any value in setting up pybots for py3k?

[Thomas Wouters]

In addition to the breakages because of Python 3.0 features and bugs, there
currently isn't a way to deal with most of those breakages, except by
forking your code in 2.x and 3.x versions. You can't write a non-bare except
statement that works in 2.x and 3.x, for instance. I'd say it's still too
early, but we're getting there -- most of the 3.0 features are in, and the
2.6-compatibility-mode is being worked on (slowly, but still.) When they're
in, people could have a buildbot setup that tests the same source in
3.0-to-be and 2.6-to-be (and older released Python versions, if they really
want to see a lot of errors.) such a setup would probably catch a lot of 3.0and
2.6 bugs, too ;-)
