typeof(this) and subclasses

[Serg Kovrov]

Hello D-people =)

Is there a way to get type of subclass in method defined in superclass, 
but called in subclass?

Here a class hierarchy:
> class Foo
> {
>   static typeof(this) create()
>   {
>     // ... some init code
>     return new typeof(this)(init);
>   }
> }
> 
> class FooBar : Foo
> {
>   /* FooBar doesn't overriding create() */
> }

and I'd like to create them as follows:
> auto f = Foo.create();    // f is instance of Foo
> auto b = FooBar.create(); // b should be instance of FooBar

But, because of 'typeof(this)' appears to be evaluated where it defined 
instead of where it called (sorry for possible misuse of terminology, 
but I hope you got my idea), 'b' is type of 'Foo' instead of desired 
'FooBar'.
