[INFO] [stdout] warning: use of deprecated associated function `std::vec::Vec::<T, A>::remove_item`: Removing the first item equal to a needle is already easily possible with iterators and the current Vec methods. Furthermore, having a method for one particular case of removal (linear search, only the first item, no swap remove) but not for others is inconsistent. This method will be removed soon.
