# src/status: a run's exit status. A run that found errors exits 1, so a# shell, the gate or an editor can tell without reading the output. `IO.die`# is what sets the code; its message goes to stderr and the findings are# already printed, so it is empty here (the runtime still ends it with a# newline: one blank line on stderr is the whole cost).import Base# exit 1 when the run found errors, else fall through (exit 0)def stop(bad: Bool) -> IO(Unit):  # noqa: L001 IO: exit status  match bad:    case True{}:      IO.die(Unit, 1, "")    case False{}:      IO.pure(Unit, Unit{})
