Ive a related couple of questions:<br><br>Whats with the word &#39;Data&#39;? Almost every Haskell module seems to be under Data.  I dont get exactly the usage of the word.<br><br>Also is there some easy way of browsing up and down the hackage hierarchical structure?<br>
[I know about hoogle and hayoo. I perhaps dont know how to use them well]<br>
