note seacloud <p>Thanks for this tight little tutorial. I'm still trying to wrap my inexperienced head around parts of it. However, in working the first example, I discovered a typo:</p> <p>You wrote<br> <blockquote> <code>join(' '),@revletters;</code> </blockquote> I think it should be <br> <blockquote> <code>join(' ',@revletters);</code> </blockquote> (I merely changed the location of the closing parenthesis)</p> <p>Cheers!</p> 1641 1641
