On the downside: This is absolutely true. All of those conversions would be the first up against the well when the revolution comes.
On the upside: I imagine a compiler warning could be pretty reasonably whipped up to detect these, and after the dust cleared, we’d be able to just try Int32(foo) and either the initializer would exist, or it wouldn’t, and it wouldn’t be necessary to bust out a playground and test to see if it’ll actually work every time you want to cast something to a number type that’s not your basic Int or Float.
