What happens with string literals? Are they implicitly converted to NSString as
necessary? Which of the following will be legal?
import Foundation
func s(_ str: String) { }
func ns(_ str: NSString) { }
let str: String = "foo"
let nsstr: NSString = "foo"
NSLog("foo")
NSLog(str)
NSLog(nsstr)
s("foo")
s(str)
s(nsstr)
ns("foo")
ns(str)
ns(nsstr)
