Is there some flow operator to make this less verbose?:

val response = readPacketFlow().first { response -> response is Acknowledgement }
when (response) {
	Acknowledgement -> true
	else -> false
}

Edit: I would like to return true or false from flow if the first item matches a given predicate.

I think that codepiece isn't correct. Response can never be anything other than Acknowledgment, because if the flow cant find Acknowledgment, it will throw an exception

[Orhan Tozan]

So response is of type Acknowledgment

True. I would like to return true or false from flow if the first item matches a given predicate. So if the first item is not of type Acknowledgement, it should return false

[Lilly]

I guess this would be my best option:

return when (readPacketFlow().first()) {
	Acknowledgement -> true
	else -> false
}

return readPacketFlow().first() is Acknowledgement
