Too bad the optimization isn't that smart:

var mainCount = 0
mainCount++

thread {
    while( true ) {
        println(mainCount)
        Thread.sleep(1000)
    }
}

could work without reference too, but the compiler generates it anyway.

Thx, how would it work without reference?

fun testLambda( block : () -> Unit ) { thread { while( true ) { block() Thread.sleep( 1000 ) } } }

Well in my example

mainCount

isn't modified after it "leaks", so no reference is needed.

If mainCount was passed by value to the generated class, how would the generated class see the latest value?

Oh ok, got it
