    but they have to be asked and/or possibly given finished patches

    and i think the desire to work on android and javascript backends means that often JVM changes aren't really seen as interesting by the kotlin team

    because it'd be years before they'd be willing to set the min java version to e.g. 9

    i raised the same concern with Sveta at JavaOne, actually. she said post-1.0 which is now, thankfully. it’ll take some weird language semantics to make this work perhaps...

    that probably belongs in #C0B8Q383C , rather than #C0B9K7EP2

    Copy code
    Local delegated properties will allow you to define a local variable as a delegated property:
fun foo() { val x by lazy { … } }

    @kmruiz:
    Typealiases are going to support boundaries? Kind of: typealias Foo = out Bar
    No. Note that 
    out Bar
    is not a "type" per se in Kotlin.

    the 
    List
    type is covariant, so 
    List<out PendingTask>
    is same as 
    List<PendingTask>
  • d

    dmitry.petrov

    04/15/2016, 2:12 PM
    Yes, 
    List<out PendingTask>
    is a type (comment from @yole regarding 
    List
    variance is valid, though).

    We might consider "type projection aliases" as an additional feature if there're enough compelling use cases for them.

    reading the latest blog post I was wondering: is there any plan around introspection for delegated properties (aka a way to access the delegated class from the property)?

    04/16/2016, 6:54 AM
    possibly. we don’t have a specific design at this time, but it’s not out of scope

    @kmruiz: what we definitely DO NOT want in Kotlin is dependent types and type-level programming. So, if what you mean is an ability to write something like (in an imaginary Kolin/Scala mix):
    Copy code
    interface DepValue {
  typealias V = out Any
  val value: V
}
fun depFun(v: DepValue): v.V = v.value // NB type of depFun(v) depends on run-time value of v
    then the answer is "no".

    @dmitry.petrov: I love Scala but this is one of the things that I prefer to not have in Kotlin 😛. It's too magic.

    In your example, 
    PostInModeration
    is used in 
    in
    position. Wonder what that should actually be...
