    is there a way to get a view of an 
    Input
    from kotlinx-io that is limited to a certain length? I would implement my own but the 
    AbstractInput
    constructor looks like it takes some weird parameters that would be hard to extract from the 
    Input
    interface

    Colleagues, we opensourced a couple of libraries for kotlin coroutines and will be grateful for feedback in the form of issues and pull requests: https://github.com/epam/CoroutinesCache

    Might there be a elegant kotlin way to replace a sublist with another sublist? Tried cutting the 
    toReplace
    part out with this code snipped to replace it (the original type is not 
    Int
    ). But that doesn't look very clean. Also when you convert the list to a mutable list and remove the 
    toReplace
    part it does'nt look very elegant.
    Copy code
    fun replaceInList(list: List<Int>, toReplace: List<Int>, replacement: List<Int>) = with(list) {
        subList(0, indexOf(toReplace.first)) + replacement + subList(indexOf(toReplace.last) + 1, size) 
    }

    I have a config class in Kotlin that has a nullable boolean, and I'm trying to reference it from Java. I do that like this: 
    boolean isTransparent = config.isTransparentToolbar();
    However, I get a lint warning that unboxing isTransparentToolbar() could cause an NPE. So I tried this: 
    config.isTransparentToolbar() != null && config.isTransparentToolbar()
    But I still have the lint warning. Am I missing something?

    If 
    isTransparentToolbar
    is a mutable property, it could be null after the null-check has passed

    I think it would need to be 
    config.isTransparentToolbar() == Boolean.TRUE

    that doesn’t work great in all situations, though, so take it with a grain of salt

    Yep, this is somewhat of a painpoint… It would be great if each class, be it Java or Kotlin, has an implicit default empty Companion object, if one is not explicitly defined (much like a default constructor is implicitly defined)…. one can wish…

    Wow, my library wasn’t working because T::class.java.newInstance() wasn’t the same as T::class.objectInstance… Took me pretty long to find this problem 😞

    if you do bad math, but good marketing, you can say that Kotling progressed by 66% from last year

    Is Kotlin’s nested function compiled with an external function embedded in an inline function?😂

    Is there some way to make the copy function of a data class the receiver of function?

    I have been wondering for a long time why incremental compilation does not work in my mixed Java/Kotlin Gradle project. With the new 
    kotlin.build.report.verbose=true
    option in Kotlin 1.3.30 I was able to isolate the problem and create a test case. If this ever starts working, I will be able to cut my coffee consumption by a significant margin 🙂. I suspect this affects quite a few people. If you are one of those, please upvote https://youtrack.jetbrains.com/issue/KT-30980

    Copy code
    val totalRows: Long = resultSet.totalRows // actually primitive long (big query java sdk)

if (totalRows == 0) { // doesn't compile
if (totalRows < 1) { // compiles
if (totalRows == 0L) { // compiles
