What would you change in C?

It's the time for the next revision of the C standard and for some reason they want your advice. What do you add, remove, rename, etc ?

I thought that's how switch statements are optimized by the compiler. I could be wrong here.

Scoped pre-processor definitions.
#{
# define hello (int)1
int test(){
    return hello;
}
#}

int test2(){
    return hello; // causes a compiler error, hello is undefined at the end of the scope
}
