You can use anonymous function or a lambda as follows

fun main(args: Array<String>) {

    fun something(exec: Boolean, func: () -> Unit) {
        if(exec) {
            func()
        }
    }

    //Anonymous function
    something(true, fun() {
        println("bleh")
    })

    //Lambda
    something(true) {
        println("bleh")
    }

}
