Describing dispatch scenarios is confusing, and spelling out the code is wordy. In an attempt to keep this document clear and compact, I'll use a short hand to describe the declaration scenarios.

Short hand:

T  = Type (class / struct / enum)
ST = Sub Type (only applies to classes)
P  = Protocol
M1.T = Type from the other module

Requiring Proactive Overrides for Default Protocol Implementations

Requiring Proactive Overrides for Default Protocol Implementations

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


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. *** BK: Saying it does not affect implies to me that it's optional. ***
