Hi! Please review the changes.

[rust-highfive]

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @jonathandturner (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

@jonathandturner I have committed only file which is Lib.rs, the other commit "Merge remote-tracking branch 'refs/remotes/rust-lang/master'" is automatically getting committed in. Please advice.

Please update corresponding tests and squash your commits

You can read about adding the additional tests in my blog post in the "Extra credit" section.

I went through the document. A small doubt, I could not find the files E0435, E0437 or E0438 under "rust/src/test/compile-fail", can I create files using the example provided in lubrustc_resolve\diagnostics.rs? Please advice.

[GuillaumeGomez]

They exist: E0435, E0437 and E0438. Update your branch to last rust-lang/master version.

[shyamsundarb-arch]

I will create a new pull request with squashed commits.
