A modern programming language that makes developers happier.

kotlinlang

I have found documentation on how to invoke garbage collector manually for testing purposes here:
<https://youtrack.jetbrains.com/issue/KT-44132/Memory-leaks-detected-in-Kotlin-Native-framework-when-using-call#focus=Comments-27-4688317.0-0>

However, I haven’t been able to figure out how to import the internal library.  I have added

```    sourceSets {
        all {
            languageSettings.optIn("kotlin.RequiresOptIn")
            languageSettings.optIn("kotlin.native.internal.InternalForKotlinNative")
        }
        // .... 
    }```
But I’m still not able to find anything in the `internal` package.  Do I need to import anything else?
