Good point. That's probably what it comes down to.

Personally I think loops, macros, etc could easily be done in XML.

<LOOP start='0' end ='100' step ='1' index='x'>
  ....
</LOOP>

<MACRO>
<PARAM name='foo' default='bar'/>
<PARAM name='baz' default='7'/>
...
</MACRO>

But then again there could be many ways to do things.
