These can be solved with a static ctor.  Essentially, any static  
initializers must be evaluatable at compile-time.  I know that in the most  
recent compiler classes have entered this realm, but I don't know the  
conditions on when they can be used.

The accepted way:

class Bar {
   static Foo f;
   static this() { f = new Foo(); }
}

static Foo g;

static this()
{
    g = new Foo();
}
