Tip: Guice Multibinder & Scala Set

I am using Guice Multibinder with Scala and this took me way too long to think up. To make things nice I want Scala Sets not Java Sets. So the following is a nice way to do it, make a constructor with Java types and call the one with Scala types.

import scala.collection.mutable.{Set => MutableSet}
import scala.collection.JavaConversions._

class MyClass( val t:MutableSet[T] ) {
@Inject() def this( t:java.util.Set[T] ) = this( asScalaSet(t) )
