As others have no doubt pointed out, if you want them back then define the operators yourself.

There were two characters to differentiate an addition from a subtraction, now there is only one (`+= 1`, `-= 1`). Also the character keys are very close in the US keyboard so it is easier to make a mistake and is not as simple as the previous solution when I typed two times the same key.

There's something very good at it. In most cases they are to be certain. But in some things they regret later. Now I see that many of us want to replace the `??` operator to something else. I'm wondering the next steps... To replace the `&&`, `||` and `!` operator with `and`, `or`, `not`?
