what is the return value of a method fun error(field: String, value: String) is it Nothing?

[marstran]

christophsturm: If you follow it with a block, it is by default Unit. If you follow it with =, it will be inferred by the expression on the right hand side.

Also note that having a return type of Nothing means that the function never actually returns, ie. it always throws an exception.

fun loopieLoop() : Nothing {
    while (true) {
      println()
    }
