#### 2.7.2 Block Comments

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.

The block comment markers must appear alone as the only characters on a line (excepting whitespace) in order to be parsed correctly.
