Hi Wesley,

I suspect that this might be easier if you construct nested templates in your model rather than in the view (templates). But, although it doesn't occur to me exactly how to do this at the moment, using first and rest functions and doing the typical functional programming thing of using recursion to iterate down the list might do it.

maybe you need to call a recursive template that starts with a list of names:

<func(f=first(names), others=rest(names))>

where

func(f,others) ::= "<f>(<func(f=first(others), others=rest(others))>)"

 try something like this.
