https://forums.swift.org/t/accepted-se-0242-synthesize-default-values-for-the-memberwise-initializer/21475

Proposal Accepted SE-0242 is accepted, with a request that the original proposal be amended for clarification of actual behavior. The Core Team felt that the proposal should more explicitly illustrate the actual behavior in a few specific cases, as this was the crux of some of the back-and-forth in the review thread.
