@Centril Argh, I wish we could exclude copies of the Rust repo! |

@rfcbot fcp merge Seems like a good idea. I propose we do this -- I also propose that we land before FCP expires, as is our wont for smaller things. |

Team member @nikomatsakis has proposed to merge this. The next step is review by the rest of the tagged teams:
No concerns currently listed. Once a majority of reviewers approve (and none object), this will enter its final comment period.

resolve: Filter away macro prelude in modules with `#[no_implicit_prelude]` on 2018 edition
This is a tiny thing.
For historical reasons macro prelude (macros from `#[macro_use] extern crate ...`, including `extern crate std`) is still available in modules with `#[no_implicit_prelude]`.
This PR provides proper isolation and removes those names from scope.
`#[no_implicit_prelude]` modules still have built-in types (`u8`), built-in attributes (`#[inline]`) and built-in macros (`env!("PATH")`) in scope. We can introduce some `#[no_implicit_prelude_at_all]` to remove those as well, but that's a separate issue.
The change is done only on 2018 edition for backward compatibility.
I'm pretty sure this can be done on 2015 as well because `#[no_implicit_prelude]` is rarely used, but I don't want to go through the crater/deprecation process right now, maybe later.

Accepted for beta backport by T-compiler. Small change, breaking for 2018, which makes it fairly important. |
