Introducing Role Keywords to Protocol Implementations to Reduce Code Errors

• Proposal: SE-TBD
• Author(s): Olivier Halligon, Caleb Davenport, Brian King, Erica Sadun
• Status: tbd
• Review manager: tbd

Introduction

This proposal enhances protocol safety at compile time by incorporating role keywords to discourage two categories of potential user errors. This proposal can be phased in first over time and language release.
