How to make a C++ intention list

I would like to make an intention list like python does.

list = [1,2,3,4]
newList = [ i * 2 for i in list ] 

Using std,iterator and lambda function, it should be possible to do the same things in one line.

std::vector<int> list = {1,2,3,4} ;
std::vector<int> newList =

Could you complete it ?

Answer Source

std::transform lets you transform values and put them somewhere else:

std::vector<int> list = {1,2,3,4};
std::vector<int> newList;

    [](int x) { return x * 2; });

But really, C++ is not the language for conciseness.
