/**
* A marker trait indicating that the <code>Throwable</code> it is mixed
* into is intended for flow control.
*
* <p>Note that <code>Throwable</code> subclasses which extend this trait
* may extend any other <code>Throwable</code> subclass (eg.
* <code>RuntimeException</code>) and are not required to extend
* <code>Throwable</code> directly.</p>
*
* <p>Instances of <code>Throwable</code> subclasses marked in
* this way should not normally be caught. Where catch-all behaviour is
* required <code>ControlThrowable</code>s should be propagated, for
* example,</p>
*
* <pre>
* import scala.util.control.ControlThrowable
*
* try {
* // Body might throw arbitrarily
* } catch {
* case ce : ControlThrowable => throw ce // propagate
* case t : Exception => log(t) // log and suppress
* </pre>
