Research direction
Run rustfmt against tests/ui/parser/survive-peano-lesson-queue.rs and confirm that formatting does not terminate. Start by tracing the formatter path used for this parser input; done means rustfmt completes instead of running indefinitely, with coverage for the regression if the repository's existing tests support it.
