Requiring Proactive Overrides for Default Protocol Implementations

• Proposal: tbd
• Author(s): Erica Sadun
• Status: tbd

Introduction

This proposal enhances protocol implementation safety. It incorporates two keywords that cooperate with compiler checks to limit "near miss" implementation errors and accidental member overrides. This is a strictly syntactic system intended to provide greater safety at compile time, and would not affect existing compiled code bases.
