$! is not classified as a binary character right now, is it?
Of course it's possible but I'd just say why this particular symbol?

It does not look mathematical either. Or do you love C/C++ so much?

Note that ~= has same meaning in Matlab.

There are other possibilities like /=�� or <> (Fortran 95, ADA), even the long form =/=.

But frankly, I don't buy this kind of change, for the sake of looking like some {} language, making such a deep change is overkill.

In any case, a big -1 for !=��

+1 ... hmmm err... I mean -1...hmmm ok +1 for the -1. Ok, I guess I suck at math.

+1
But then I also want to suggest #!== for negating identity.
