Takes 1 more character, that's bloat.

Thanks, i hate it
I saw while(i --> 0) in someone else's code and thought wth is this --> operator? Then I realized it's while(i-- > 0) and thought cool, I gotta do this!
this is incredibly cursed. i love it.
Isn't the evaluated value different from the expression? i++ returns the value of i before increasing. i-=-1 would return the value after it has been increased. Wouldn't it be more correct to make it equal to ++i
And that's why post- and pre-increment is non-existant in Python and Rust. It's an easy source for bugs for a noncritical abbreviation🤷
They're especially also a source of bugs, because they encourage manually incrementing indices and manually accessing array positions, which is almost never actually sensible.
In the languages I know, i-=-1 or x=3 are not expressions, but rather statements, so they do not evaluate to a value.
So, this would be a compiler error:
a = (x=3)
Well, not all languages allow for fun programming :)
