Subteam report: libs 2015-10-02

Highlights

This week the primary libs focus was resolving several outstanding issues and PRs that needed a team-wide decision. We also discussed the following nursery nominations:

• compiletest
• net2-rs
• lazy_static

along with more general process clarifications around the nursery.

We also saw a proposal for moving liblibc out of the nursery, while simultaneously greatly clarifying its purpose and design:

• PR #1291: RFC: Promote the libc crate from the nursery

There has been significant discussion around no_std and friends, which is currently in FCP:

• FCP Issue #27701: Tracking issue for libcore stabilization

Other FCP issues for 1.5 stabilization are available here; please leave feedback!

Finally, we accepted the RFC on wildcard dependencies in crates.io:

• PR #1241: Forbid wildcard dependencies on crates.io

No RFCs moved into FCP this week.
