</div>As far as I can see, the live version of `the section you mention`_ on<br>
<a href="http://learnyouahaskell.com" target="_blank">learnyouahaskell.com</a> does not contain this text - it doesn't have the<br>
"ghci> " at the beginning of the line. Besides what others have said in<br>
response to your question, I would add that you should make sure to read<br>
LYAH on the website if possible - other sources might be out of date, as<br>
I think the author does update the website version from time to time.<br>
