I would like to take advantage of some features in the current Velocity release, specifically the 'hasNext' looping test enabling for example, the conditional addition of a trailing ', ' when building a list of javascript values.

This would allow:

#foreach( $customer in $customerList )
    $customer.Name#if( $velocityHasNext ),#end
#end

But would require a velocity.properties addition:

directive.foreach.iterator.name = velocityHasNext

Enabling this would reduce the need for 'rendering' code to be done within Java classes when it doesn't need to be.
