Could this be
let stack = &self.sess.included_mod_stack;
for stack.slice(i, stack.len()).iter().advance |m| {
err.push_str(fmt!("%? -> ", m.to_str()));
}? (Possibly even moving the stack binding out of the match to use it there.)

Sounds good, rebased patch is coming up.
Unfortunately I couldn't move the let stack = .. out of the match due to dynamic borrow checker errors. 😡
