[swift-users] Why can't we get `URL` equal on the same path?

[Keith Smiley]

Just want to mention that there are some differences between `NSURL` and `URL`.
Here's an example from the repl:

```
  1> import Foundation
  2> NSURL(string: "")
$R0: NSURL? = "" {
  ObjectiveC.NSObject = {}
}
  3> URL(string: "")
$R1: URL? = nil
```
