If the suggestion to use :: instead of : in the pattern isn't correct, a second resolution error will be emitted.

I think extracting the code to "join" two patterns into a function might make the code cleaner.

old_path.segments.extend(path.segments) or something of the sort would be nicer, perhaps?

What do you think of this?

                                                    path.segments = old_path
                                                        .segments
                                                        .iter()
                                                        .cloned()
                                                        .chain(take(&mut path.segments))
                                                        .collect();

Is this truly MachineApplicable? We don't really check with the resolver here that the constructed pattern will match, do we?
