That is a very narrow legalistic way of looking at things. If you don't
like the word "equality", substitute a more generic word, such as
"sameness" We continually have threads about when to use "==" and when
to use "is". Clearly, there is confusion about them. Adding another
way to test for sameness will just increase the confusion.
