Actually that would be a bad symbol pairing (the equals/notequals
parallel is not correct, A = B does not imply B != A). A better one

But that would break backwards compatibility which above you are
telling me is a big deal for the operators that people don't actually
use!

So, for sheer conservative curmudgoenliness, I would suggest we leave
~ and @ as they are.
