Hey, I stumbled upon something strange -> when calling a Channel from a suspending lambda...the Channel get stucked...is this expected?:

fun randomFunction() {
    val channel = Channel<String>()
    val lambda = suspend {
        channel.send("abc")
    }

    runBlocking(randomContext) {
        lambda()

        println(channel.receive())
    }
}

That's normal, you're using a rendezvous channel (zero capacity) so the call to send will suspend until something receives the item. It would happen even without the lambda.

Thx for the answer...I had not in mind that send can also suspended.
