Making SetTimeout and co. globally available by default about k6 HOT 5 OPEN

For clarification and my understanding, what does the target user-experience look like?

My assumption reading this is:

// No need to import the `k6/timers` module

export default function () {
    setTimeout(...)  // timer functions are available in the runtime "natively", like in v8 browser runtimes
    setInterval(...)
    clearTimeout(...)
    clearInterval(...)
 }

If so, I think that makes a lot of sense, and although I'm not completely set on that, it is also something we might want to consider also for "Web APIs" we integrate in the future (webcrypto, streams, fetch (if we do), etc...) to provide a user-experience close to what is available in other runtimes.

Yes, that will be a thing that users will be able to do - without needing to import anything

I feel that having these functions globally accessible is what users will expect. However, I can't say I'm a JavaScript expert, so I am unsure if my feelings are relevant.

Similar to @olegbespalov, not a JS expert neither, but I guess that's what experienced JS users would expect, while for the rest it doesn't matter. So 👍🏻

there is no event loop in Goja (TMK). So I am not sure who/what would call the global setInterval. Using Goja for this lib seems like a terrible mistake and frankly I am gonna run as far as I can in another direction (no offense but hopefully this helps other people..)
