Kotlin Multiple Layer it Reference

Question

How do you reference the second layer "it" from the third layer without creating a new val/var? I know you can do val mydata = it and then do mydata.id.toString() I was just wondering is there something in Kotlin that can let me reference an it from a higher level?

data.arrayresults.forEach {
    val result = it

    result.myData.let {
        val itemView - inflater.inflate(R.layout.somelayout)

        itemView.setOnClickListener(View.OnClickListener {

            // the it references the view but I want it to reference the result.myData
            SomeActivity.startActivity(context, it.id.toString())
        })
    }
}

No, the it symbol always references the innermost implicit single lambda parameter.

To resolve this, and also to improve the code readability, use named lambda parameters every time when you have nested lambdas with parameters, as suggested in the Coding conventions:

data.arrayresults.forEach { result ->    
    result.myData.let { myData ->
        val itemView - inflater.inflate(R.layout.somelayout)

        itemView.setOnClickListener(View.OnClickListener { view ->

            // the it references the view but I want it to reference the result.myData
            SomeActivity.startActivity(context, myData.id.toString())
        })
    }
}
