Could you be a bit more specific what your point is, e.g. which
specific files you mean? I agree that not everything is clear yet, but
I don't think that things are completely confusing.

To restate: I think a task is a concrete thing to do, including steps
etc. while a goal is a largeish collection of tasks. Right now I think
we should collect goals and tasks that we think we can manage in the
mid-term. Exactly which of the tasks should be made into releases is
an orthogonal issue, IMO. Maybe we could add a new kind of file
release-XXX.txt that points to various tasks? On the other hand I am
not sure it makes sense to plan more than one release ahead.

To say a bit about the next release: My opinion is (and I think others
agreed during the Gothenburg sprint, see
) that the next release should be really mostly a compliance and
testing release. Which means that to make the release we should set up
better test infrastructure and test "real-world-applications" on
PyPy's Python interpreter, as well as write some mid-sized apps for
our special features. In a sense that would be a rather boring release
with mostly only many incremental features but on the other hand with
a lot of stability improvements. How does this sound?
