Prepitch: Character integer literals

I feel like a similar argument can be made to motivate compile-time checking of URL , rather than first "going through" String .

This should absolutely be built on top of compile-time constant expressions and could be done entirely in the library once the feature is implemented and powerful enough. I'd love to see a @compilerEvaluable init(_ url: StaticString) that does exactly what you describe.
