intellij is telling me this isn't valid

function invocation expected

an overriding function is not allowed to specify defaultt parameters

hmm

can I do it on the interface?

oh i missed it's an override

you're probably forced to

Consumer

then

so it's not possible to use defaults with interfaces?

Is there a specific reason code like this fails to compile? Restrict suspension seems overly restrictive to me in this case:

@RestrictsSuspension
interface Scope<A> {
  suspend fun test()
}

open class MyScope<A> : Scope<A> {
  override suspend fun test() = TODO("placeholder")
}

class OtherScope<A> : MyScope<A>() {
  override suspend fun test() = super.test() // Fails because of restricted suspension
}

I was looking at the kotlin standard library, and I came across this comment on the function

List<T>.lastIndexOf(element: T)

:

@Suppress("EXTENSION_SHADOWED_BY_MEMBER") // false warning, extension takes precedence in some cases
public fun <@kotlin.internal.OnlyInputTypes T> List<T>.lastIndexOf(element: T): Int {
    return lastIndexOf(element)
}

"false warning, extension takes precedence in some cases" In kotlin.collections, list is defined with this method:

public interface List<out E> : Collection<E> {

    /*Other things*/

    public fun lastIndexOf(element: @UnsafeVariance E): Int

    /*Other things*/
}

Why is this a false warning? When does the extension ever take precedence? Thanks in advance!

I have enough resources...

but thanks for the replies

Hi guys! I am starting a project using kotlin, ktor and koin. My project is oriented to TDD and I am having problems with DI in unit tests. The exception I am facing is the following:

Dokka Preview Based on Kotlin 1.4.0-RC The following post is written by Paweł Marks and Kamil Doległo. Every programming ecosystem needs documentation to thrive.

Is there a method like

toggleElement(element: E)

in the Kotlin's collections stdlib? This method removes the element if exists and adds if not. I know that I can write it myself since it's straightforward, but I thought maybe Kotlin has such a method.
