Recreating ruby's n.times operator on Kotlin. This is for fun, in all seriousness use the repeat(n) operator

ruby_times_in_kotlin.kt

fun main() {
    // normal function
    repeat(3) { print("Yay $it ") }
    // => Yay 0 Yay 1 Yay 2 
  
    2.times { print("Looop ") }
    // => Looop Looop 
    10.times { print("$it ") }
    // => 0 1 2 3 4 5 6 7 8 9
}

// Note: times is already defined as multiplication in Kotlin as well, 
// I just named it as such to recreate the Ruby syntax
infix fun Int.times(fn: (Int) -> Unit) = repeat(this, fn)

It's also trivial to write this without using repeat (that's how I initially approached it).

infix fun Int.times(fn: (Int) -> Unit) {
   var i = 0
   while (i < this) {
       fn(i)
       i++
   }
}
