It does work, the problem is that scoped returns a Voldemort 
type, so you have to use 
typeof(scoped!SomeClass(someConstructorArgs)) to declare a field. 
Gets really annoying when doing it with any class that doesn't 
have a zero-argument constructor, especially in generic code.

class Foo {}

class Bar {
     typeof(scoped!Foo()) foo;
     this() {
         foo = scoped!Foo();
     }
}
