>It is useful to distinguish between consuming an element and only jumping to it. So you would have an ptr[i++] for consuming the current token, but not, when you are switching to another token.

So, it's trivial to do it with a function. Or a macro.

    int adv(int *i){
        int t = *i;
        (*i) = t + 1;
        return t;
    }
    
    while(i < 10)
        printf("%d\n", adv(&i));

Not to mention, iterators and all that jazz.

The point is, you don't need assignment to return a value to have this.

Can you give a non-contrived example where you really need it?

It's not that I "prefer stylistic choices of Go", it's that I hate to have undefined behavior in language spec which is easy to stumble into - the cost of the "stylistic choice" that C made doesn't make that choice justified.
