I don't think that would work. Because then this won't work:

extern (Objective-C)
class NSObject
{
    NSObject init() @selector("init");
    static NSObject alloc() @selector("alloc");
}

extern (Objective-C)
class Foo : NSObject
{
    override Foo init() @selector("init");
    override static Foo alloc() @selector("alloc");

    void foo() @selector("foo") { }
}

In Foo we override "init" and "alloc" just to get the correct static return
type. I think the above example has to work.
