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

[Trent Nadeau]

I think both of the camel-case conventions are much easier to read, and
both are fine with me. I slightly prefer the former (UpperCamelCase), but
that just might be because the only languages I've used with annotations
that also have camel-case conventions (Java and C#) both use UpperCamelCase.
