Haskell Hackers,<div><br></div><div>I&#39;m pretty comfortable with all of Haskell 98 (and 2010, really). But I&#39;ve always sort of avoided extensions. I realize that this is a bit silly and if I want to continue learning, it probably means delving into the extensions. Which ones are the most important to know from a practical point of view? And which ones from a {Language,Category,Math}-theoretical point of view? (Any other interesting/important points of view I&#39;m missing? :D )</div>
