[swift-evolution] [Proposal] function "return" optional keyword.

[Radosław Pietruszewski]

I honestly don’t have a problem with having to say `return` inside functions. That’s not necessarily a -1, but I’m reluctant to say +1 when _even I_ don’t really have the problem with extra verbosity.

*However*, as others pointed out, having to type `return` is a bit tiring in the context of a computer property’s “get”:
