continue_vs_return.kt

Does it bother anyone else that repeat(x) doesn’t count as a loop so you have to use `return` instead of `continue`/`break`?

Do you use `break` or `continue` in `forEach`?

no because I can’t, but it would make sense to me to do so

though I understand that it’s not technically a loop

Well it doesn’t for me because you should know that you’re using a lambda, which has a much bigger cost than a normal loop

Well, `repeat` is inline and doesn't really cost more than a `for` or `while` loop

But the semantics are different. `repeat` is a just a higher order function (a function that takes another one, called a lambda), while `for`, `while`, `do`/`while` are part of the control flow, similar to `if`/`else`, but with the added fact that they can loop.

so doesn’t that imply by Gael’s logic that `continue` should be applicable?

No, `continue` works only for raw control flow constructs like `while`

skipping code is not possible. In a lambda, you can only run, return or throw. returning to the lambda works the same as `continue` though, so in practice, there's not much difference

Well, skipping code is possible with `if`, but you can't jump out of a lambda out of nowhere, unless that lambda is inline and you return to the function it's inlined in.
