1.It makes most of the operations of std::list slower;
2.std::forward_list don't have this method. This makes people very confused.
3.the method splice() becomes much slower.
4.We know our library couldn't make people very confused. That was why we 
didn't define the operator[] in the std::list<>;
5.The function of this method can be easily implied by programmers 
themselves. We know this function had been defined clearly in cpp11, but in 
the cpp98, its time-complexity is not defined clearly. For this reason, in 
the past we almost didn't use it. So  I think this change won't make so 
many codes invalid.
