[swift-evolution] Reconsider ++ and -- operators removal and prevent other well-known operators from change

Strong -1 to this proposal.
If your code is in dire need of ++/--, you can always define them yourself using the language affordances. (Unlike, say, defining your own C-style for loop.)
Other than that, ++/-- were a crufty legacy carryover from C, and their disadvantages are adequately described in the rationale portion of the proposal.
?? and ?: are in no imminent danger, and even if they were their removal should be debated on the merits of those specific operators.
Finally, if people are going to try and re-open the pre-SE-0005 proposals for retroactive discussion, maybe we should have a 'community comments' period for each of them and just get it over with.

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. Using Erica's way of saying certain things: I do not love the removal of `++` and `--`.

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`? I’m not "loving" this as well.
