front_insert_iterator::operator=

Appends (pushes) a value onto the front of the container.

);

• _Val
  The value to be assigned to the container.

반환 값

A reference to the last element inserted at the front of the container.

The first member operator evaluates container.push_front(_Val), then returns *this.

The second member operator evaluates

container->push_front((typename Container::value_type&&)_Val),

then returns *this.
