I think it's the right thing for Swift. My main concern would be naming. If they're both named `reduce`, I suspect that will stress the type checker trying to pick an overload based on the context of the closure expression. We're stuck with `reduce` having the value-in-return-out formulation for Swift 3 compatibility; if that weren't the case, I'd argue we only need the `inout` form.
