Pontoneer is a proposal for adding more support for python extensions (mapping protocol, number protocol and others).

This is currently blocked by [[BUG] Recent mojo versions hang when exporting recursive types to python · Issue #6123 · modular/modular · GitHub](https://github.com/modular/modular/issues/6123)

It is different (and possibly better) approach than this [PR](https://github.com/modular/modular/pull/5562) I proposed back in November.

Feedback appreciated 🙇

Could I get a review on this PR: [Add pontoneer v0.3.6 by winding-lines · Pull Request #223 · modular/modular-community · GitHub](https://github.com/modular/modular-community/pull/223)

Maybe @Caroline ?
