Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safety, concurrency, and speed. This is a weekly summary of its progress and community. Want something mentioned? Tweet us at @ThisWeekInRust or send us an email! Want to get involved? We love contributions.

This Week in Rust is openly developed on GitHub. If you find any errors in this week's issue, please submit a PR.

Final Comment Period

Every week the teams announce a 'final comment period' for RFCs which are reaching a decision. Express your opinions now. This week's RFCs entering FCP are:

• Expand the std::net module. Expand the surface area of std::net to bind more low-level interfaces and provide more advanced customization and configuration of sockets.
• Rename connect to join.
• Replace slice::tail()/init() with new methods.
• Redirect stdio of child processes to open file handles.
• Allow macros in types.
• Allow closure expressions to expand to a & or &mut temporary. Modify the || expression sugar so that it can expand to either F, &F, or &mut F, where F is a fresh struct type implementing one of the Fn/FnMut/FnOnce traits.

New RFCs

• Add a high-level intermediate representation (HIR) to the compiler..
• Style: How should we format function declarations?.
• Stabilize the #![no_std] attribute.
• Anonymous/placeholder lifetime '_. Allow using an undeclared '_ wherever an explicit lifetime can be used, but is optional, such as function argument/return types and any path inside a function.
• Create IntoRaw{Fd, Socket, Handle} trait to complement AsRaw*.
• Allow changing the default allocator. Add support to the compiler to override the default allocator, allowing a different allocator to be used by default in Rust programs.
• Propose Interior data-type, to allow moves out of the dropped value during the drop hook.
