Entire blocks of code can be commented by enclosing the code between matching ‘#{’ and ‘#}’ or ‘%{’ and ‘%}’ markers. For example,
     function quick_countdown
       # Count down for main rocket engines
       disp(3);
      #{
       disp(2);
       disp(1);
      #}
       disp("Blast Off!");  # Rocket leaves pad
     endfunction
   will produce a very quick countdown from '3' to 'Blast Off' as the
lines "disp(2);" and "disp(1);" won't be executed.
