def each
  loop do
    option_name, option_argument = get_option
    break if option_name == nil
    yield option_name, option_argument
  end
end

Iterator version of ‘get’.

The block is called repeatedly with two arguments: The first is the option name. The second is the argument which followed it (if any). Example: (‘–opt’, ‘value’)

The option name is always converted to the first (preferred) name given in the original options to GetoptLong.new.
