kotlinlang

just, read the docs: <https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/split.html>

those red lines come with an error message

’cause that one-liner I posted is valid Kotlin according to my IntelliJ

`none of these following functions can be called using the arguments supplied` :?

`
```"asd".split(" ", limit = 2)```
` works `
```"asd".split(" ", 2)```
` doesn’t :S

`.split()` with a string delimiter is a _three_ argument function call — if you skip an argument, you can’t supply the last argument positionally

You have to realize that the Java `String#split` takes a regex as first parameter.  Kotlin (rightfully) requires to pass a Regex instead of a String if the parameter is a regex, and there is the drop-in 2 param equivalent in Kotlin stdlib.  Thus, you should use `log.split(" ".toRegex(), 2)` instead of using the 3-param variant that takes a String instead of a regex (which does not exist in the Java stdlib). Of course in your example both would work because your regex `" "` does not contain anything which is not matched literally.
