Tracking Issue for autodiff #124509
Description
This is a tracking issue for the automatic differentiation experiment ("autodiff").
The feature gate for the issue will be #![feature(autodiff)].
About tracking issues
Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions. A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the relevant feature gate label. Discussion comments will get marked as off-topic or deleted. Repeated discussions on the tracking issue may lead to the tracking issue getting locked.

We discussed this on the lang triage call today and were happy to see this move forward as an experiment. I'll be continuing as the liaison for this, so please let me know whenever anything is needed to keep this moving along.

Hi! This is a tracking issue, which isn't meant for technical discussion.
Can you two please open threads in the #wg-autodiff zulip instead? Happy to answer questions there.
