&gt; <br />&gt; Hi Patrick - I like it!  I&#39;m still a Haskell beginner, but even to me, your code seems very clear and easy to understand. I&#39;ve been thinking of doing some simple parsers too, so I was wondering - may I use this code of yours as a base for them? <br /><br />Sure, anyone here can use the code if they have any interest in it.<br /><br />Patrick<br /><br />&gt; <br />&gt; Well done, and thanks for doing this!<br />&gt; <br />&gt; - Andy<br />&gt;
