Here is the draft proposal: https://github.com/DevAndArtist/swift-evolution/blob/single_expression_optional_return/proposals/nnnn-single-expression-optional-return.md
Did I covered everything case? If you find some mistakes feel free to provide feedback so I can fix the proposal before I submit a PR. -- Adrian Zubarev Sent with Airmail Am 31.
