Hi,

I am having problems with adding an element to a '@' vector in rust 0.4.

The following works fine with a "~" vector but not with a '@' vector:

                         let mut objects_1 : &mut ~[Object] =  &mut ~[];
                         let mut objects_2 : &mut @[Object] =  &mut @[];

                         objects_1.push(Bat_(bat));
                         objects_2.push(Bat_(bat));  // Line 124

Appending to an `@` vector would require copying the entire vector, just as with arrays in Java. (We should still probably support `push` on it with this performance caveat, but that's the reason why we don't right now.)

If you want to append to a vector, you probably want the `DVec` type, or a ~vector.
