How do I call a Scala Object method using reflection?

Question

say, I have the following:

trait SomeTrait {
  def someMethod: String;
}

object SomeObject extends SomeTrait {
  def someMethod = \"something\";
}

Since scala 2.10, we can use the reflection of Module:

import scala.reflect.runtime.universe

val runtimeMirror = universe.runtimeMirror(getClass.getClassLoader)
val module = runtimeMirror.staticModule("SomeObject")
val obj = runtimeMirror.reflectModule(module)
val someTrait:SomeTrait = obj.instance.asInstanceOf[SomeTrait]  
someTrait.someMethod
