  Argument from verbosity is seldom a good argument in programming.
Just because something is shorter doesn't necessarily mean it's better.

  Anyways, many languages have constructs to make that shorter. Curiously,
the next C++ standard will introduce constructs that allow you to write:

  for(auto& v: list1) list2.push_back(v);
