I guess it would have been nice to have a

getCompletedOrNull()

that returns a null instead of throwing... so currently the only way is to

runCatching { deferred.getCompleted() }.getOrElse { defaultValue }

?

You can check

isCompleted

instead

So here's your

poll

method:

fun <T: Any> Deferred<T>.poll() = if (isCompleted) getCompleted() else null

Thanks that's true, probably better than catching the exception, but I wonder if it would be useful in the lib itself? Why is it there in Channels but not in Deferred?
