Delegator

[bioinfornatics]

hi,
In ruby we can delegate some method. by example:
---- Ruby ----
class MineArray
  include Forwardable
  def_delegators: @array, :[], :[]=, :each_with_index, :length

  def initialize( array )
    @array = array
  end
end
-------------

this code delegate opIndexAssign opIndex, length ... attribute to his
member.

This save time, bug and line. You do not to have to write a code as:
void opIndexAssign( size_t index, T item){
        array[index] = item;
}

thanks
