 However, I quickly realised some parts are slowly becoming outdated as Haskell continues to evolve. That is why, with the author's blessing, I decided to create this open-source fork to enable the Haskell community to participate in preserving and maintaining this awesome resource for the future times.

 <p>Notice the type of <span class="fixed">find</span>. Its result is <span class="fixed">Maybe a</span>. That's kind of like having the type of <span class="fixed">[a]</span>, only a value of the type <span class="fixed">Maybe</span> can contain either no elements or one element, whereas a list can contain no elements, one element or several elements.</p>
-<p>Remember when we were searching for the first time our stock went over $1000. We did <span class="fixed">head (dropWhile (\(val,y,m,d) -&gt; val &lt; 1000) stock)</span>. Remember that <span class="fixed">head</span> is not really safe. What would happen if our stock never went over $1000? Our application of <span class="fixed">dropWhile</span> would return an empty list and getting the head of an empty list would result in an error. However, if we rewrote that as <span class="fixed">find (\(val,y,m,d) -&gt; val &gt; 1000) stock</span>, we'd be much safer. If our stock never went over $1000 (so if no element satisfied the predicate), we'd get back a <span class="fixed">Nothing</span>. But there was a valid answer in that list, we'd get, say, <span class="fixed">Just (1001.4,2008,9,4)</span>.
