resolve: Scale back hard-coded extern prelude additions on 2015 edition https://github.com/rust-lang/rust/pull/54404 stabilized `feature(extern_prelude)` on 2015 edition, including the hard-coded parts not passed with `--extern`. First of all, I'd want to confirm that this is intended stabilization, rather than a part of the "extended beta" scheme that's going to be reverted before releasing stable. (EDIT: to clarify - this is a question, I'm \*asking\* for confirmation, rather than give it.) Second, on 2015 edition extern prelude is not so fundamentally tied to imports and is a mere convenience, so this PR scales them back to the uncontroversial subset. The "uncontroversial subset" means that if libcore is injected it brings `core` into prelude, if libstd is injected it brings `std` and `core` into prelude. On 2015 edition this can be implemented through the library prelude (rather than hard-coding in the compiler) right now, I'll do it in a follow-up PR. UPDATE: The change is done for both 2015 and 2018 editions now as discussed below. Closes https://github.com/rust-lang/rust/issues/53166 |
