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

[Craig Cruden]

I looked at the discussion and it looked like they were discussion two things combined.
   - inferred return type (on function signature) 
   - and omitting return on the return.

I agree with Chris on the fact that the function should have the type of return specified on the signature and not inferred since it is useful for API documentation to know that ahead of time on a strongly typed language.

What is not necessary is actually forcing people to type return “x” on the last line - since “return” is rather redundant and clutter for those people of a functional programming paradigm point of view.
