+Title: This Week in Rust 59
+Date: 2014-12-01
+Category: This Week in Rust
+
+Hello and welcome to another issue of *This Week in Rust*!
+[Rust](http://rust-lang.org) is a systems language pursuing the trifecta:
+safe, concurrent, and fast. This is a weekly summary of its progress and
+community. Want something mentioned? [Send me an
+email!](mailto:corey@octayn.net?subject=This%20Week%20in%20Rust%20Suggestion)
+Want to get involved? [We love
+contributions](https://github.com/mozilla/rust/wiki/Note-guide-for-new-contributors).
+
+# What's cooking on master?
+
+71 pull requests were [merged in the last week][1].
+
+[1]: https://github.com/rust-lang/rust/pulls?q=is%3Apr+is%3Amerged+updated%3A2014-11-24..2014-12-01
+
+## Breaking Changes
+
+* [libgetopts has had][getopts] some public re-exports removed, Fail_ renamed to Fail,
+and getopts::FailType has been removed.
+* BinarySearchResult's variants [are no longer re-exported][bstenum], and must be accessed
+through the enum itself.
+* [libsync is dead][ripsync]. Long live `std::sync` and `std::comm`. All uses of libsync
+should be able to cleanly migrate to these two modules.
+* MaybeOwned[Vector] has been deprecated [in favour of Cow][cowabunga]. See the PR for
+full details of all the consequences.
+* Non-failing `unwrap` methods [have been renamed][into-winner] to `into_inner`, as
+per [RFC 430][rfc430]
+* You can [no longer invoke Dark Magicks][never4get] and match on an enum struct variant
+as if it were a tuple. As a consequence, Rust is no longer a useful programming language.
+* non-ASCII lifetime identifiers [have been feature-gated][whatishappening]. Rust is now
+only of academic interest, and lacks any practical applications.

+
+## Other Changes
+
+* CowString now [implements Str][cowstr] as MaybeOwned did.
+* Unboxed closure captures are [now avaiable in debuginfo][debuginfo].
+* tomjakubowski has taught Rustdoc about [several][tomja1] of [rust's][tomja2] new
+[features][tomja3].
+* Some missing collection iterators [have][iter1] [been][iter2] [added][iter3].
+* The inner contents of Buffered io types [are now accessible mutably][buffers].
+* Tests [now add less useless whitespace][notabs] to your terminal's output.
+* Statically allocated TLS keys are now [explicitly leaked][leaky].
+* Fields of consts are [now transitevly interpretted as const][constmemaybe],
+allowing e.g. `[T, ..MY_TUPLE.0]`.
+* `::::` [no longer appears][nonono] in module paths in debug logs.
+* AtomicOption now [correctly requires `Send`][atomic] for memory safety.
+* japaric has DST-ified more of the standard libs
+* The iterator module has been [partially stabalized][iterstab].
+* Platform-specific io modules `std::or::unix` and `std::os::windows`
+[have been added][i-oh-my] for working with lower-level `io` details
+like file descriptors, SOCKETS, HANDLES, etc.
+* Slice iterators can now [be converted to slices][sliceit] via `as_slice`.
+* Rng [now supports][random-floats] `next_f64` and `next_f32`.

+# Approved RFC's
+
+* [Disallow type/lifetime parameter shadowing][rfc459]: Rarely what you want, confusing when it happens.
+* [Add "function name macro"][rfc466]: This RFC proposes the addition of a function! macro that expands to the function it's used in. This will greatly help error reporting.
+* [extension trait conventions][rfc445]: This is a conventions RFC establishing a definition and naming convention for extension traits: `FooExt`.

+
+# New RFC's
+
+* [Stabilize `std::{c_str, c_vec}`][rfc494]: Stabilize the std::{c_str, c_vec} modules by re-working their interfaces and refocusing each primitive for one particular task.
+* [Error Reform and Failure Box][rfc492]: This RFC proposes changes to the `Error` trait and the introduction of a `Failure<T>` wrapper type for errors and modifications to the `Error` trait for better error interoperability and debugging support. [Reddit][red492]
+* [Remove the `[]` notation for taking a whole slice][rfc491]: &* has emerged as less strange and more idomatic
+* [Change DST syntax to `T: Sized?`][rfc490]: Change the syntax for dynamically sized type parameters from `Sized? T` to `T: Sized?`, and change the syntax for traits for dynamically sized types to `trait Foo: Sized?`. Extend this new syntax to work with `where` clauses.
+* [rename `lifetime` to `lifespan`][rfc487]: 'nuff said
+* [std::ascii reform][rfc486]: Move the `std::ascii::Ascii` type and related traits to a new Cargo package on crates.io, and instead expose its functionality for `u8`, `[u8]`, `char`, and `str` types. [Reddit][red487]
+* [Make brackets optional for single attributes][rfc484]: This is an alternative to #483: instead of changing attributes to `@`, just make the brackets optional for `#`.
+* [Change attribute syntax to @foo][rfc483]: Change attribute syntax from `#[foo]` and `#![foo]` to `@foo` and `@!foo`. [Reddit][red483]
