Problem calling overloaded functions with function parameters

1

Hi,

The following fail to compile with Overload resolution ambiguity: internal final fun Foo.repeat(n : jet.Int, block : () -> Unit) : Unit defined in root package internal final fun Foo.repeat(n : jet.Int, block : (jet.Int) -> Unit) : Unit defined in root package

class Foo
fun Foo.repeat(n : Int, block: ()->Unit) {
     for (i in 1 .. n)
          block()
}
fun Foo.repeat(n : Int, block: (Int)->Unit) {
     for(i in (1 .. n))
          block(i)
}



fun main(args : Array<String>) {

     Foo().repeat(3){ println(“test”) }          // case 1

     Foo().repeat(3){ i -> println(“test $i”) }  // case 2

}


What’s is interesting is that if I comment out just the “case 1” line, the program will run “case 2” without problem.

So the question I have is overloaded functions that has function as parameter officially supported? If yes, this would be a bug then?

Thanks,
Zemian

This is a bug. A workaround is to explicitly specify parameters in function literals.

Please, report to the tracker. Thanks
