Trying to compile this

enum Node<T> {
    Empty,
    Leaf(T),
}

impl<T> Node<T> {
    fn new() -> @Node<T> {
        @Empty
    }
}

fn main() {
    let n = Node::new();
}

Errors out with this

$ rustc construct.rs 
construct.rs:13:12: 13:21 error: unresolved name
construct.rs:13     let n = Node::new();
                            ^~~~~~~~~
construct.rs:13:12: 13:21 error: use of undeclared module `Node`
construct.rs:13     let n = Node::new();
                            ^~~~~~~~~

@lucian1900: You still have to mark static methods with the static keyword. Otherwise the compiler interprets it as using the deprecated implicit self.

Oh, I see. Hopefully 'static' will be deprecated soon as well :)
