How do I pass the constructor of a nested class?

```class Base() {
    class Nested() {
    }
}

funWithCtor(::Base) // works
funWithCtor(::Base.Nested) // doesn't work
funWithCtor(::Nested) // works if: import Outer.Nested```

Hmm, that doesn't work right for me either

Works fine for me: <https://pl.kotl.in/IrPAmrRSX>

<@U7V1LUY64> what does “doesn’t work” mean here?

```fun funWithCtor(ctor: KFunction1&lt;Param, ReturnType&gt;) {
    // ...
}```

This gives a type mismatch if using the nested constructor, but works fine with the base class constructor. Need to use KFunction1 rather than () -&gt; Any.

Having a bad time copy/pasting the error message.

That doesn’t even work with `Base` in your example, because `KFunction1` expects 1 parameter. Neither `Base()` nor `Base.Nested()` have a parameter.

Still works fine for me: <https://pl.kotl.in/gylSVL9Gz>

Sorry, Marc, just trying to simplify from my full code. Will see about reproducing it at <http://pl.kotl.in|pl.kotl.in>

Interestingly, this works fine on the playground, but IDEA is complaining:

"Type mismatch: inferred type is Param but Outer was expected"

Are you sure you’re not dealing with an `inner class` somewhere?

No, I straight up copy/pasted that snippet from playground into IDEA

ah funny, I see different code in the playground
after resetting site data I see the correct one now :smile:

Does it compile in the IDE?
If yes then the difference is because of New Type Inference.

Also doesn’t work in the Playground with Kotlin 1.4.0-rc

Ah yes, never used the playground before (new to Kotlin). I see indeed when switched to 1.4.0-rc on the playground with the JS target (which I'm using in IDEA) it gives the same error.

Yeah looks like a bug.

`Outer::Nested::invoke` works :thinking_face:

Thanks, threw it on YT - <https://youtrack.jetbrains.com/issue/KT-41038>
