[swift-evolution] [Discussion] Modernizing Attribute Case and Attribute Argument Naming

Do you have an alternative suggestion? I can add the following to the Alternatives Considered:

Using lowercase for attributes names becomes confusing with longer compound examples. For example `warnunusedresult`
looks a lot like a continuous string of lowercase characters. I recommend the Swift team consider introducing upper camel case
for attributes to match the Cocoa members (UIApplicationMain, NSManaged, NSCopying, NSApplicationMain, IBAction, IBDesignable, IBInspectable, IBOutlet) or lower
camel case to avoid this issue:

@AutoClosure, @Available, @ObjC, @NoEscape, @NonObjC, @NoReturn, @Testable, @WarnUnusedResult, @Convention, @NoReturn


@autoClosure, @available, @objC, @noEscape, @nonObjC, @noReturn, @testable, @warnUnusedResult, @convention, @noReturn
