$! 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 != 2014-06-26 10:47 GMT+02:00 Max Leske <maxleske@gmail.com>:

Hi,
I would like to make a suggestion that may lead to a long debate but let's go: What do you think about deprecating ~= and replace it with != for example? Why? In mathematics the symbol ~ is used for equivalence. To me (and I think any newcomer to Smalltalk) the first guess of the meaning of ~= is equivalent to => missed. The meaning is totally different: "Answer whether the receiver and the argument do not represent the same object.â
+1 But then I also want to suggest #!== for negating identity.
I never used this method because it is too confusing for me. I prefer to
use (a = b) not or (a = b) ifFalse:.
So, the discussion is open ...
