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

Hello everybody.

I see Swift as a member of “C family" (a granddaughter/grandson of C, a
daughter/son of Objective-C). OK, she/he is different and has her/his own
personality like a daughter/son should be and have, but I still like to see
Swift and recognize some traces that I know are things that became from C.

This said, I would like to say that after the removal of `++` and `--` my
code becomes less readable and more prone to errors. 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 `--`.

I do not know how far the Swift is to the adolescence, but it is certain
that teenagers are rebels. 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`? I’m not "loving" this as well.

Are these changes really necessary for the Swift evolution? Is it the
better path to deny its origin and to try to fix what is not broken? I
would like you to think about it.

There are many other things that really need to be improved and repaired
and other things needed to are created. Those mentioned here in this
message does not seem to fit it.
