Look at these snippets and tell me which is more verbose.

a &= 0x80;

a = a and 0x80

IDK, reassignement to vars is not my cup of tea.

I've ran into many scenarios where I wanted a bitwise-OR + assign operator, or a bitwise AND + assign operator

The infix functions make those impossible

It's not just about being verbose. It's also f***ing unreadable in anything that's more complex than just a simple bit-test.

So it turns out this is entirely possible to achieve in Kotlin. The println executes. No concurrency involved. I may have missed some fine print but to me this is a case of something that "cannot be null" being very, very null in the "throws nullptr and crashes your program" sense. Really puzzling until you realize that you indirectly called this from an init block. Even worse if you're newish to Kotlin and thought init was basically the body of the primary constructor. (It's already a weird "feature" with special syntax so I wouldn't have been surprised.) So I guess I just stop using primary constructors so I can actually write constructor code without seeing weird crap like this?

Is anyone addressing this?

Can you rephrase it as a proposal rather than a complaint? I mean, think about how it could be designed and implemented, provide case studies, may be even draft an algorithm?

I'll give it a shot - I'm surprised it has not happened yet. And clearly frustrated given the fuss Kotlin makes over null safety. I guess this belongs in YouTrack

can we work with kotlin alongside php in android studio ?

what happened to the language spec? is there still a plan to produce a spec?

@pniederw It was mentioned in this video: https://vimeo.com/215556547

Thanks @arocnies. I think standardization is a step beyond having a language spec.

Right now there doesn’t appear to be any detailed language documentation.

@leonardootto not sure there is a “why” behind every name, but you can find more information on the island here: https://en.wikipedia.org/wiki/Kotlin_Island

Thanks Peter, but didn't find this information in wikipedia. 🙂

as I said, I don’t think there is an (interesting) reason behind every (island) name.

I found some information using auto translation from Russian. Thanks @pniederw

what did you find?

Sorry for the text, it's auto-translating.

@pniederw Ah yes, it was on standardization not a spec (my bad). The grammar is documented here: https://kotlinlang.org/docs/reference/grammar.html, although that's not what you're asking about

It’s a start. What I feel is missing is a spec for, or at least detailed documentation of, language semantics.

Writing a spec is a lot of work. A partly competed spec is available on guthub, but it hasn't been actively maintained recently. We are looking into ways of changing this. If you can recommend people who can work on the spec, please send me a PM. Thanks

Is there a way to convert this to working Kotlin code?

interface Action<T extends Throwable> {
	void doSomething() throws T;
}

When I paste this converted snippet to try.kotlinlang.org

interface Action<T : Throwable> {
	@Throws(T::class)
	fun doSomething() 
}

I see next error msg: Can not use 'T' as reified type parameter. Use a class instead.

There are no checked exceptions in Kotlin

But as I understand @Throws annotation allows to use them
