    that's how receiver lambdas work

    Actually both these version are far less effective than the traditional approach.

    anyway, next time someone asks "why not scala?", point them to this snippet 😂

    why? the apply thing should have zero overhead
  • m

    It should but in this case it has an overhead of allocating two additional objects.

    which ones?

    kotlin/jvm/internal/Ref$ObjectRef

    what's that?
  • m

    This class allows mutating values captured by a lambda function.

    I though inline methods are completely inlined?
  • m

    It is completely inlined from technical point of view simple smile

    this should compile to the equivalent of
    Copy code
    String $this = b;
b = a;
a = $this;
  • m

    Seems at this point Kotlin compiler isn’t smart enough to generated such code.

    The extra allocation will probably be removed during JIT thanks to escape analysis

    Interesting talk, C# looks like the inverse of Java (upppercase variables and lowercase classes) with some Kotlin functionality superimposed on top of it, haha The returning of tuples looks awesome, didn't know Kotlin had it. Always wanted such functionality, glad Kotlin has it as well!!!

    my theory, C# was largely born out of the MS/Sun lawsuit. once MS got beat down in court, they took the Java work they’d already done, tinkered a bit, called it C#. change enough of the cosmetic stuff (cases of variable, methods, etc) to make it different and moved on.

    I’m not too crazy about tuples myself since inevitably, I always end up creating a class for them anyway (and with Kotlin’s 
    data
    classes, there’s no reason not to)

    The C# API simply comes from the Win16 API, which uses uppercases for methods (we were using C at the time)
  • c

    11/03/2016, 6:14 PM
    I suspect that uppercasing would be the harder thing for me to get over in C#, the rest is pretty straightforward 🙂

    C# learned a lot of lessons from Java's design. It's made its own pitfalls along the way, to be sure, but it did try to deal with a lot of the direct pain points of Java.

    That being said, it also picked up baggage from its C-family lineage 😞

    Even Java avoided some of the coarser bits, there.

    I feel like C# has been able to mature more strongly as a language than Java has, though. They've been very careful about making additions that don't create great gulfs of deprecation, while still making those additions very practical for future dev.

    And, of course, Kotlin has picked up and improved many of the features that C# has accumulated and refined over the years.

    Is there an official place to order Kotlin stickers from yet? Or other merchandise? :)

    @janvladimirmostert To be precise, Kotlin has 
    data
    class like 
    Pair
    and 
    Triple
    and destructuring. That's not the same as tuples and is also less efficient than what C# has because the JVM doesn't have value types yet

    Also would like to be able to order official Kotlin stickers and stuff. I still have a sticker on my laptop that's the pre-1.0 logo. Would like to update that

    I've seen images of JetBrains handing out the new logo stickers at events. But I want to give them money for it 🙂
