Consider these situations:
int a = 0;
int b = a++ + a++;
int c = (a++) + (a++);
int d = a++ + (a++);
int e = (a++) + a++;
b == c == d == e == 0. I understand based on a previous bug about sequence
points in C++ but I think a common-sense approach takes precident here. If 'a'
were a user-defined class with the operator++ (postfix), how could the user
mimic such behaviour, namely b == c == d == e == 0? In fact they couldn't. The
proper solution is then to have b == c == d == e == 1.
