Thanks for weighing in!

The benefit of `5.times` vs `repeat 5` is that the former is (and can easily be) defined in Swift, not as a language-level feature. OTOH `repeat 5` is a bit more useful because it allows returning/breaking/etc.

But I also understand the argument that this feature isn’t worth it at all. (There’s already a lot of libraries extending stdlib with things of this sort!)
