[swift-evolution] URL Literals

[Erica Sadun]

I'd prefer to see a literal URL than a Foundation URL that is string-initializable. I don't see a URL literal as being in any way necessarily tightly coupled with a Foundation URL type. The point of a literal is that it is inherently typeless and checked at compile time. A color literal depending on context can be a UIColor or NSColor but that's not specified outside of the use context. The code is portable and cross platform.

Various improvements to the Foundation API (and URL in particular) have been proposed here, but if I remember correctly, the stated goal was first to have a complete Swift version of Foundation, preserving the existing API as exactly as possible with no additions or subtractions, and only then to consider Swifty evolution of the APIs. I don't think the first step is complete yet.
