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. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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.

It looks like the syntax use foo:: as bar; is still accepted, could that be explicitly rejected as well?

[Potpourri]

Sorry for deleted branch, i was wrong.
In case use foo:: as bar;, as parsed as part of module path, and not keyword.
I fixed it and created new pr.

[alexcrichton]

Did you mean to re-open the PR? (it's still closed)

I think you can re-open by recreating the branch, but otherwise feel free to open a new PR

[Potpourri]

[alexcrichton]

Ah well, feel free to open a new one!
