    <h3>MOD</h3>
    
      Note that this is the true modulus operation, rather than JS's default remainder operation. Checking parity over negative integers becomes easier this way, for example.
  
negative.code: 
    <strong>_</strong> reads 'read', as in read-only
  
    <strong>$</strong> reads 'space variable', or 'spacevar'
  
  <h4>Combo elements:</h4>

    <strong>&gt;$</strong> reads 'put spacevar'
  
    <strong>__</strong> reads 'read last'
