    Hey so, does anybody else intentionally leave compiler errors on their branches while they're working so that when they come back to their work they'll have a tool telling them explicitly what they were working on? Is there a kotlin language feature that will let me do this? I figured some kind of use-anywhere style annotation might be more elegant. something like
    @CompilerFailure("my custom message")

    Hello everyone I am stuck on a kotlin coroutine. Appreciate if someone can help me on that. I am launching a coroutine that after a specified delay display a counter value on the screen. job = launch(UI) { var count= 0 while (true) { textView.text = "${count++}" delay(200L) } } } Now on screen rotation I want UI keeps getting updated with correct counter value. Does someone has any idea how to resume the job on configuration(e.g. screen rotation) change.

    Is there an easy way to create a view of multiple lists? Like, I would like to be able to iterate over "list" A to iterate over lists B, C and D, without it being an actual separate collection, just a view. Without building my own iterators and stuff, I just want to know if there's another cool thing in the stdlib I don't know about

    -field of an enum to loosen up the validation.

    Hey there, I have an interesting clash between Java and Kotlin. Maybe you can help? I have a Java interface I'm trying to implement in Kotlin...
    public interface Identifiable<T> {
      T getId();
    }
    I've tried the following...
    class Product(override val id: String): Identifiable<String>
    But i get an error
    id overrides nothing
    Then I tried:
    class Product(val id: String): Identifiable<String> {
      fun getId(): String = id
    }
    But, of course, you get a JVM conflict
    The following declarations have the same JVM signature 'public final <get-id>(): String' and 'public open getId(): String'
    I found that making
    id
    private works but that's less than ideal:
    class Product(private val id: String): Identifiable<String> {
      fun getId(): String = id
    }

    Probably got the wrong place to ask this, but here it goes nothing. If Kotlin was designed without the JVM in mind would we have
    nullables
    and the `?
    /
    !!
    /
    ?:` operators? i.e Is it safe to consider these as merely interoperability features? Specially given that there are safer ways to define default cases (with
    sealed classes
    for example)

    If
    property
    is not null safe, the second would break. Also, I don't recall there having a
    map
    for non-collection types.

I believe not, I don't see how can bytecode for that be generated. Non-static method calls in bytecode must have a pointer to the caller object.
