Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

New RFCs

macro. Semantic "private in public" enforcement. Enforce that public APIs do not expose private definitions at the semantic level, while allowing the use of private aliases and blanket implementations for convenience and automation.
