This one is a heavy `'tcx` user. Two interesting ones: This one had the `'tcx` declared on the function, despite the trait taking a `'tcx`: ```diff -impl Visitor<'_> for UsedLocals { +impl<'tcx> Visitor<'tcx> for UsedLocals { fn visit_statement(&mut self, statement: &Statement<'tcx>, location: Location) { ``` This one use in-band for one, and underscore for the other: ```diff -pub fn remove_dead_blocks(tcx: TyCtxt<'tcx>, body: &mut Body<'_>) { +pub fn remove_dead_blocks<'tcx>(tcx: TyCtxt<'tcx>, body: &mut Body<'tcx>) { ```
