+    <question>
+    What is the "standard" way to write a simple loop in
+Scala?
+<code>
+   for (val i &lt;- Iterator.range(1,1000000)
+</code>
+or
+<code>
+   var i = 1;
+   while (i&lt;=1000000){ ...; i=i+1; }
+</code>
+</question>
+<answer>
+Both are fine, but in the current implementation the second one should be more efficient. </answer>

+<question>how can I catch exceptions in Scala?</question> 
+
+<answer> You have to use standard pattern matching here (Java's
+"catch" clauses are really nothing more than a limited form of pattern
+matching).
+
+<code>
+   try { 
+   ... 
+   } catch {
+     case e: Exception  => ... 
+     case e:IOException => ...
+   }
+</code>

+<question>I want to use the Ord interface to handle Double, Int, and Char. Why doesn't it work ?</question>

+<answer>Currently, the class scala.Double (and all other value classes) are
+*not* a subclass of scala.Ord. This is an implementation restriction
