I have this map private val routes = mapOf<Regex, (vararg args: String) -> LaunchAction?>(

I would like to accept a variable number of arguments in that anonymous function defined as the map’s value, how can I do that? I’m not allowed to set a modifier like vararg there

vararg is syntatic sugar for Arrays, so use args: Array<String> instead like so:

private val routes = mapOf<Regex, (args: Array<String>) -> LaunchAction?>(

As the old adage goes

Don't use an array unless you need an array. If you don't know if you need an array, you don't need an array.

That is to say, I'd probably just stick with List<String>.

I'm assuming that they're already using vararg elsewhere and so they expect arrays everywhere
