Sounds good to me.

As always, it is a good idea to start tagging things that should be in the

There's a couple of nice PRs pending that depend on it with only a pure
Python fallback. While I'm pretty happy with how the use of Pythran is
shaping up, I think we should leave it as an optional build dependency only
for this release, and try to make it non-optional afterwards. There's
always the chance we'll find something unexpected in the release, and
there's Windows build thing that needs sorting out - it works for all
wheels, but Ilhan is having some trouble with a local build setup.

Cheers,
Ralf
