Super-trait operator doesn't work within trait

[aomader]

Consider the following simple trait example:

pub trait Indexable<T>: Index<uint, T> {
    fn index2(&self, i: uint) -> &T {
        // Doesn't work:
        // self[i]

        // Does work
        self.index(&i)
    }
}

As you can see by the comments, using the []-operator on self doesn't work directly. Instead, one has to call the index function manually.
It seems like something is broken with operators and super-traits.

Its an autoref problem. The following code:

fn main(){}

pub trait Indexable<T>: Index<uint, T>  {
    fn index2(&self, i: uint) -> &T {
        &(*self)[i]
    }
}

does work.

pub trait Indexable<T>: std::ops::Index<usize, Output = T> {
    fn index2(&self, i: usize) -> &T {
        &self[i]
    }
}
fn main() {}

works fine now, adding needstest.
