```flow { while (true) { delay(1000) emit(Unit) } }``` ?

flow {
    while (true) {
        delay(1000)
        emit(Unit)
    }
}

?

That is the cool thing about coroutines (and Flows). You can code your own special flow behaviors, operators, etc in a very imperative/sequential way. 🙂

Note that this cannot be used for a timer because it doesn't take into account the execution time delay adding up, nor emit taking some time to resume (because the lambda of collect would take some time).

Hi, coming over from another Slack-Thread about internal "collect" vs. launchIn {} , just to be clear on flow consumption:
the canonical way to consume is:
a) toList()
b) launchIn(...)
.. else ?
