[Pitch] Last expression as return value

[tera]

I still believe this is a great feature provided it is disabled for discardable results:

    func cook(vegetable: Vegetable) -> Vegetable {
        print("Bzzzz")
        vegetable.cook() // ❌Error: discardableResult functions need explicit return!
    }
    func cook2(vegetable: Vegetable) -> Vegetable {
        print("Bzzzz")
        Vegetable() // ✅ fine
    }

thus fixing the regression mentioned in the headline post and making it less non-obvious. This feature naturally promotes "single expression rule" to "last expression rule" (single line is the last line as well) thus making the language conceptually simpler.

If this has generated such a big debate on swift forums

Yeha, soon to be the all time winner
