Not least due to DrupalX's multi-line statements, it would of course be quite nice to now add some comments within a statement block to better explain what's going on. DrupalX adds this feature as well:
{%
//Use these settings only for category "business"
if category=="business";
set color="#800000"; //Dark red
set align="right"; //Text-align right
set columns=3; //Three-column layout
endif;
%}
