That's a bit of an exaggeration. For instance, consider this CS101 for loop:

for (int i=1; i < 10; i++) {

Here's the same loop in XSLT:

<xsl:template name="CS101">
   <xsl:param name="index" select="1"/>
   <xsl:if test="index &lt;= 10">
     <xsl:value-of select="$index"/>
     <xsl:call-template name="CS101">
       <xsl:param name="index" select="$index + 1"/>

It's a little more complicated, but most of that is a result of the 
XML syntax, not recursion or the lack of modifiable variables. And 
it's certainly not two pages more complicated.

If we were to rewrite the functional solution in Java for a more 
accurate comparison of functional vs. imperative approaches you'd 
have something like this:

public void loop(int i) {
   if (i < 10) loop(i+1);

That may be less familiar but it's hardly more fundamentally complex.
