There was a problem hiding this comment.
I argue that the new behavior should be exercised in the expected-behavior test file.

Added test for this, so, it should be ready to merge. It seems that an FCP is required so we probably want to start that now. |

r? @zackmdavis ping from triage @clarcharr you have failing tests to resolve |
|
@Dylan-DPC ...I resolved the tests. This is ready for FCP. |

r? @SimonSapin |

This seems like an obvious improvement to me, but it adds a stable API: @rfcbot fcp merge |

Team member @SimonSapin has proposed to merge this. The next step is review by the rest of the tagged team members: No concerns currently listed. Once a majority of reviewers approve (and none object), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up! See this document for info about what commands tagged team members can give me. |

ping from triage @simonpersson / @rust-lang/libs any updates on this? |

Version 1.35.0 (2019-05-23)
==========================
Language
--------
- [`FnOnce`, `FnMut`, and the `Fn` traits are now implemented for `Box<FnOnce>`,
`Box<FnMut>`, and `Box<Fn>` respectively.][59500]
- [You can now coerce closures into unsafe function pointers.][59580] e.g.
```rust
unsafe fn call_unsafe(func: unsafe fn()) {
func()
}
pub fn main() {
unsafe { call_unsafe(|| {}); }
}
```
Compiler
--------
- [Added the `armv6-unknown-freebsd-gnueabihf` and
`armv7-unknown-freebsd-gnueabihf` targets.][58080]
- [Added the `wasm32-unknown-wasi` target.][59464]
Libraries
---------
- [`Thread` will now show its ID in `Debug` output.][59460]
- [`StdinLock`, `StdoutLock`, and `StderrLock` now implement `AsRawFd`.][59512]
- [`alloc::System` now implements `Default`.][59451]
- [Expanded `Debug` output (`{:#?}`) for structs now has a trailing comma on the
last field.][59076]
- [`char::{ToLowercase, ToUppercase}` now
implement `ExactSizeIterator`.][58778]
- [All `NonZero` numeric types now implement `FromStr`.][58717]
- [Removed the `Read` trait bounds
on the `BufReader::{get_ref, get_mut, into_inner}` methods.][58423]
- [You can now call the `dbg!` macro without any parameters to print the file
and line where it is called.][57847]
- [In place ASCII case conversions are now up to 4× faster.][59283]
e.g. `str::make_ascii_lowercase`
- [`hash_map::{OccupiedEntry, VacantEntry}` now implement `Sync`
and `Send`.][58369]
Stabilized APIs
---------------
- [`f32::copysign`]
- [`f64::copysign`]
- [`RefCell::replace_with`]
- [`RefCell::map_split`]
- [`ptr::hash`]
- [`Range::contains`]
- [`RangeFrom::contains`]
- [`RangeTo::contains`]
- [`RangeInclusive::contains`]
- [`RangeToInclusive::contains`]
- [`Option::copied`]
Cargo
-----
- [You can now set `cargo:rustc-cdylib-link-arg` at build time to pass custom
linker arguments when building a `cdylib`.][cargo/6298] Its usage is highly
platform specific.
Misc
----
- [The Rust toolchain is now available natively for musl based distros.][58575]
