// The port mirrors the reference's Python control flow closely, which
// trips a number of pedantic and nursery style lints (const-fn suggestions
// on reference-shaped helpers, boolean flag structs mirroring the
// reference's int bitmask, long matcher functions). The tree opts out of
// those two groups; everything else still denies.
