The compiler _never_ defines opCmp for you. You have to do that yourself. So, what you're suggesting would force people to define opEquals just because they defined opCmp unless they wanted to take a performance hit. And once you define opEquals, you have to define toHash. So, what you're suggesting would force a lot more code to define toHash, which will likely cause far more bugs than simply requiring that the programmer define opEquals if that's required in order to make it consistent with opEquals.
Again, you're assuming there will be a performance hit. -- /Jacob Carlborg
