That’s basically a repetition that brought no additional information to the table. The question stands. > Now, you might argue that trapping does not meet your definition of "lossy," > but it certainly causes problems in the example posed above: I’m not talking about trapping, I’m talking about losing information. As in, the reverse conversion may differ from the original value. (why do you make me define this?). Trapping is fine; it’s the right behaviour. More broadly, though, I and others would like to know why it’s *better* to have no label on Int.init(_ x: Float) than to have one. Your attitude seems to be that the status quo needs no justification, but perhaps the status quo is not a global optimum.
