[swift-evolution] [swift-evolution-announce] [Review] SE-0080: Failable Numeric Conversion Initializers

[Colin Barrett]

> Swift numeric types all currently have a family of conversion initializers. In many use cases they leave a lot to be desired. Initializing an integer type with a floating point value will truncate any fractional portion of the number. Initializing with an out-of-range value traps.


Have you considered whether it makes sense to keep these around? Maybe the failable ones should be the default, and give the other ones a more descriptive 1st argument label.
