I believe you're putting too much focus on the flow object space; it's
only part 1 of many in the translation process (even though it was
that part that kept us from splitting RPython and PyPy so far).  But
anyway as others have pointed out we can discuss such additional moves
after the main split.

That last stipulation was saying: if you install the PyPy and the
RPython repos, then you should be able to use the (older) version of
py.test that comes with PyPy in order to run tests in the RPython repo
as well.  In other words, RPython's tests should not suddenly become
dependent on newer features of py.test.


A bientôt,

Armin.
