[swift-evolution] Property Getter Return Statement

[Xiaodi Wu]

This has been brought up on the list before. For instance:

https://github.com/apple/swift-evolution/pull/608

Chris Lattner’s response at that time was:

‘Just MHO, but I consider this syntactic sugar, not a fundamental feature
that fits the goal of Swift 4 stage 2.

‘I’m also pretty opposed to doing it at any time. The rationale of
“implicit return” in closures is specifically because they are limited to a
single expression, which makes the semantics “obvious”. This was carefully
considered.’
