This is a tracking issue for the RFC "Destructuring assignment" (rust-lang/rfcs#2909).
The feature gate for the issue is #![feature(destructuring_assignment)].

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also uses 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.
