// Mixed-type comparisons between String and NSString.
// Since the compiler will implicitly bridge String to NSString, these more
// refined overloads exist to disable invalid bridging from happening.
// For example, swiftString < nsString will bridge swiftString to NSString
// and perform incorrect unicode comparison.
