Perhaps you want to tell me to remmember the index of vector element can
trace them, but vector is a sequence, you can erase any element, after
that, the indexes you remmembered can not access the correct object.
And sometimes, pointer is the fastest way to go to another object,
especially in CPU-comsuming program, keep a pointer to another object is
very important.
