Valid Forth syntax:<p><pre><code>    6 8 7 5 4 + * - + .
     -49 ok
 </code></pre>
Tell me that&#x27;s easier to read than<p><pre><code>    8+6-(4+5)*7
</code></pre>
Parenthesis can make things harder to understand if poorly used. RPN can make things harder to understand if poorly used.<p>The reverse is also true for both. Forth does not prevent bad code.
