[swift-evolution] Proposal: Add .times method to Integer type

[Brent Royal-Gordon]

I've seen it used to retry a failing operation a certain number of times:

	5.times do
		return true if do_network_call
		sleep 5
	end
	raise NetworkCallFailedError

Of course, that requires you to be able to return out of the surrounding function from the `times` loop, which you can do in Ruby but not in Swift.
