-  /** Allows to cast a value to a facade trait in a type-safe way.
-   *
-   *  Use as follows:
-   *  {{{
-   *  js.use(x).as[MyFacade]
-   *  }}}
-   *
-   *  Note that the method calls are only syntactic sugar. There is no overhead
-   *  at runtime for such an operation. Using `use(x).as[T]` is strictly
-   *  equivalent to `x.asInstanceOf[T]` if the compile time check does not fail.
-   *
-   *  This method supports both Scala classes with exports and facade types
-   *  which are structurally equivalent.
-   *
-   *  == Examples ==
-   *  Given the following facade type:
-   *  {{{
-   *  trait MyFacade extends js.Object {
-   *    def foo(x: Int): String = js.native
-   *    val bar: Int = js.native
-   *  }
-   *  }}}
-   *
-   *  We show a couple of examples:
-   *  {{{
-   *  class MyClass1 {
-   *    @JSExport
-   *    def foo(x: Int): String = x.toString
-   *
-   *    @JSExport
-   *    val bar: Int = 1
-   *  }
-   *
-   *  val x1 = new MyClass1
-   *  js.use(x1).as[MyFacade] // OK
-   *  }}}
-   *
-   *  Note that JS conventions apply: The `val bar` can be implemented with a
-   *  `def`.
-   *
-   *  {{{
-   *  class MyClass2 {
-   *    @JSExport
-   *    def foo(x: Int): String = x.toString
-   *
-   *    @JSExport
-   *    def bar: Int = 1 // def instead of val
-   *  }
-   *
-   *  val x2 = new MyClass2
-   *  js.use(x2).as[MyFacade] // OK
-   *  }}}
-   *
-   *  Missing methods or methods with wrong types will cause a compile-time
-   *  failure.
-   *
-   *  {{{
-   *  class MyClass3 {
-   *    @JSExport
-   *    def foo(x: String): String = x.toString // wrong type signature
-   *
-   *    // bar is missing
-   *  }
-   *
-   *  val x3 = new MyClass3
-   *  js.use(x2).as[MyFacade] // Fails: bar is missing and foo has wrong type
-   *  }}}
-   *
-   *  Methods must be exported, otherwise they are not taken into consideration.
-   *
-   *  {{{
-   *  class MyClass4 {
-   *    def foo(x: Int): String = x.toString
-   *
-   *    @JSExport
-   *    def bar: Int = 1 // def instead of val
-   *  }
-   *
-   *  val x4 = new MyClass4
-   *  js.use(x4).as[MyFacade] // Fails, foo is missing
-   *  }}}
-   *
-   *  Other facade types can also be used
-   *
-   *  {{{
-   *  trait MyOtherFacade extends js.Object {
-   *    def foo(x: Any): String = js.native
-   *    val bar: Int = js.native
-   *    def otherMethod(): Unit = js.native
-   *  }
-   *
-   *  val x5: MyOtherFacade = // ...
-   *  js.use(x5).as[MyFacade] // OK
-   *  }}}
-   *
-   *  == Restrictions ==
-   *  - Facade types may only be traits and not have any class ancestors
-   *  - Polymorphic methods are currently not supported
-   *  - Facade types defining an apply method cannot used (this is a JavaScript
-   *    restriction).
