You are telling me to use '==' if I choose string objects and 'is' if I

I prefer a solution that works regardless of what objects I choose for

No, it isn't as long as the string object references have a common
assignment "pedigree." Assignment (including parameter passing) is
guaranteed to preserve identity of any object.
