// The trailing-argument timer forms: Node passes the extras to the
// callback — setTimeout(cb, ms, ...args) fires cb(...args), setInterval
// delivers the same arguments EVERY tick, setImmediate(cb, ...args)
// likewise — and the one-argument setTimeout defaults its delay (the
// callback still fires exactly once). The delivered call rides the
// checked-dynamic boundary, so typed parameters see the real values.
