VelocityEngine.evaluate()?
No, i don't think there's a way to do that automatically without customizing
your velocity build. But you can fake it:
#set( $h = '#')
#set( $d = '$' )
#foreach( $element in $object1.elements )
#end
#if( !$object1 )
${h}foreach( ${d}element in $object1.elements )
${h}end
#end
