    I'd agree that keeping side-effects separate is important if you want that
as a feature of the language, and that it would be confusing for former C
coders in the similarity. I can't buy the readability argument though. 

    Personally, I find var++ infinitely more readable than var += 1. 

    Although Pascal's incr() function is probably moreso. 

    Anyway, if you're going to add a feature, += makes more sense since you
can increment by variable amounts, but it's still less readable, IMHO. 

    Of course, if you add var++, do you add ++var?
