I was actually thinking that we could rewrite methods that look like this:fn TakesANode(node: &JS<Node>) to read as follows: fn TakesANode<N: NodeBase>(node: &JS<N>) { let node: JS<Node> = NodeCast::from(node); That would enable passing any Node-derived type as a parameter; unfortunately the cast is still present in the callee, but it could clean up callers a bit.
I suspect the struct inheritance stuff that's slated for post-Rust-1.0 will help here. (Actually Nick Cameron has a partial implementation already. Perhaps we should look into merging it.)
