You can always get it wrong:
while (*dst++ = *src++) ;
!=
while (dst^++ = src^++) ;
...and:
++*dst;
!=
++dst^;
...maybe if you are used to it, it does seem marginally better (and I guess both of the above postfix examples could give warnings). But IMO the much bigger win is to have something that 99.999% of the programmers on the planet will instantly understand (and make porting code easier), instead of having them say WTF!

Fortunately, these examples don't apply to go, since go lacks pointer
arithmetic. Also, the ++ operator is changed to a statement in go, also to avoid this sort of confusion.
