Hey guys! I was quite surprised with this code:

repeat(3) {
   if (it == 0) return@repeat
   println("inside repeat")
}

it prints “inside repeat” twice instead of 0 times Why is that?

repeat(3, block)

≈

block(0); block(1); block(2)

Then is there any way to make a true break inside

repeat

or

forEach

(like we can do in regular loops)?

as they're inline functions, you can return to an outer scope:

run {
    repeat(3) {
        if (it == 0) return@run
        println("inside repeat")
    }
}

but if that's necessary, IMO you should consider using a normal

for

loop instead.

for (i in 0 until 3) {
    if (i == 0) break
    println("inside for")
}
