@orangy @ilya.gorbunov Can tell why this example provided in the docs throwing exception on try.kotlinlang.org but works fine in the IDE

inline fun <reified T> membersOf() = T::class.members

fun main(s: Array<String>) {
    println(membersOf<StringBuilder>().joinToString("\n"))
}

I have no idea. May be @udalov can help?

also in my opinion there should be an option to try the beta releases online Like an option to switch btw stable and beta

There are in the bottom-right corner

Sorry my bad on that one
