    So about this "new type inference" feature, is there some formal discussion or docs available on this? The only thing I'm able to find is Svetlana's Kotlinconf talk, and some 'informal' descriptions like in https://kotlinlang.slack.com/archives/C0922A726/p1540842295383000?thread_ts=1540837535.363900&cid=C0922A726. Since turning it on using
    -XXLanguage:+NewInference
    results in things breaking due to overload resolution ambiguity, I'm curious what the options are to mitigate this?

    what are some practical cases of inline classes though? Doesn’t typealias already kinda do what inline classes do

    someone mentioned above doing things like unit conversions. Looking at what the restrictions are, i think that might be a good use for it. It's unclear to me if you can make an inline class implement an interface though.

    i would think the above might be more efficient that
    60.seconds.inMinutes
    just because there's no overhead of class creation. Thoughts?

    i think the question was more about the kotlin-stdlib-jre7 compared to kotlin-stdlib-jdk7 and i think this is mostly a rename

    hello folks, I was trying to understand
    internal
    modifier and found that visibility is restricted to a module. And definition of module in context of gradle as per doc is :
    a Gradle source set (with the exception that the test source set can access the internal declarations of main);
    a)What does
    gradle source set
    mean? Does it mean a gradle module(talking in terms of an android project) or some subset of it? b)Do we have any advantages of using internal in a multi module project? like reduces incremental build time or so?

    This is not a directly Kotlin related question, but it can be used with Kotlin too, how do you navigate to the implementation of an abstract function, in a specific implementation class? suppose you have an
    Animal
    class that has
    abstract fun run()
    and you have
    class Dog : Anima() { //implements run }
    and you have an instance of dog and usage of
    run()
    somewhere
    kotlin
    val dog = Dog()
    dog.run()
    how do you navigate to
    run
    implementation in Dog?

    Why does actually Kotlin lacks extension functions (like
    apply
    or
    let
    ) which return
    Unit
    ? Something like
    fun <T> T.end(block: T.() -> Unit): Unit

    Was just catching up on the 1.3 announcement. I’m very excited about the unsigned ints stuff. I do a bit of protocol work. But I’m curious how they implement that on top of the JVM which does NOT have unsigned ints. Does anyone know? Are there performance implications?

    private static class InnerClass {
            private String name = "Murali";
    }
    }
    When i convert this code into kotlin using kotlin converter in IDEA i got an error at innerClass.name showing the name is private. But that works fine in Java. Please show me how to achieve the same in kotlin!
