Unicode escapes were changed in [this RFC](28aeb3c391/text/0446-es6-unicode-escapes.md) to use the ES6 \u{00FFFF} syntax with a variable number of digits from 1-6, eliminating the need for two different syntaxes for unicode literals.
I have updated The Reference and grammar.md to reflect these changes.
Hi.
Here a commit in order to add OpenBSD support to rust.
- tests status:
run-pass: test result: ok. 1879 passed; 0 failed; 24 ignored; 0 measured
run-fail: test result: ok. 81 passed; 0 failed; 5 ignored; 0 measured
compile-fail: test result: ok. 1634 passed; 0 failed; 22 ignored; 0 measured
run-pass-fulldeps: test result: ok. 22 passed; 0 failed; 1 ignored; 0 measured
compile-fail-fulldeps: test result: ok. 13 passed; 0 failed; 0 ignored; 0 measured
- The current implementation of load_self function (src/libstd/sys/unix/os.rs) isn't optimal as under OpenBSD I haven't found a reliable method to get the filename of a running process. The current implementation is enought for bootstrapping purpose.
- I have disable `run-pass/tcp-stress.rs` test under openbsd. When run manually, the test pass, but when run under `compiletest`, it timeout and echo continuoulsy `Too many open files`.
- For building with jemalloc, a more recent version of jemalloc would be mandatory. See https://github.com/jemalloc/jemalloc/pull/188 for more details.

literals.
This commits adds an associated type to the `FromStr` trait representing an
error payload for parses which do not succeed. The previous return value,
`Option<Self>` did not allow for this form of payload. After the associated type
was added, the following attributes were applied:
* `FromStr` is now stable
* `FromStr::Err` is now stable
* `FromStr::from_str` is now stable
* `StrExt::parse` is now stable
* `FromStr for bool` is now stable
* `FromStr for $float` is now stable
* `FromStr for $integral` is now stable
* Errors returned from stable `FromStr` implementations are stable
* Errors implement `Display` and `Error` (both impl blocks being `#[stable]`)
Closes#15138

Note: Do not merge until we get a newer snapshot that includes #21374
There was some type inference fallout (see 4th commit) because type inference with `a..b` is not as good as with `range(a, b)` (see #21672).
r? @alexcrichton
Fixes#19759
I'm not going to bother to do more than this, as it'll end up getting re-done as part of the reference work, but at least it's correct now.
