Hi, I wanted to play with repeat and retry provided by Schedule. But I got failure with a simple example:

fun main() {
    var counter = 0
    val io = IO.effect {
        println("Run: ${counter++}")
        counter
    }
    io.repeat(IO.concurrent(), Schedule.once(IO.monad())).fix().unsafeRunSync()
}
