Feature mostly works and is avaiable under #![feature(capture_disjoint_fields)]
We have handled all edge cases we are aware of including patterns, FRU syntax, references in move closures, handling unsafe
Migration lint for drop reordering is supported under #[deny(disjoint_capture_drop_reorder)] and is supported using rust fix.
On going work to support migration for auto-traits, and diagnostics
