Separating contexts

You can also remove context elements from a combined context if needed. To do this, you need to have a reference to the key of the element that you want to remove. For example, let's modify the previous example so that we separate the combined context:

fun main(args: Array<String>) = runBlocking {    val dispatcher = newSingleThreadContext("myDispatcher")    val handler = CoroutineExceptionHandler({ _, throwable ->        println("Error captured")        println("Message: ${throwable.message}")    })    // Combine two contexts together        val context = dispatcher + handler    // Remove one element from the context    val tmpCtx = context.minusKey(dispatcher.key)    launch(tmpCtx) {        println("Running in ${Thread.currentThread().name}")        TODO("Not implemented!" ...
