Recursive templated structs disallowed?

[Simen kjaeraas]

struct bar( T ) {
     auto baz( U )( U arg ) {
         bar!( typeof( this ) ) tmp;
         return tmp;
     }
}

void main( ) {
     bar!int n;
     n.baz( 3 );
}

This code fails with
Error: recursive template expansion for template argument bar!(int)
Now, I agree it is recursive, but it is not infinitely recursive, so
there shouldn't really be a problem.
Is this a bug? Is there a workaround?
