When you try to compile the following program, it will appear to the compiler that the local variable 'x' is assigned but never used and warnings will be issued accordingly. You can get rid of these warnings by compiling using the -nowarn flag.
<lang scala>// Kotlin JS version 1.1.4-3
fun evalWithX(expr: String, a: Double, b: Double) {
var x = a
val atA = eval(expr)
x = b
val atB = eval(expr)
return atB - atA
}
fun main(args: Array<String>) {
println(evalWithX("Math.exp(x)", 0.0, 1.0))
}</lang>
